I. Cloning: The History
A. Who was Hans Dreisch (created the first cloned
animals in the late 1800’s)
1. Dreich’s original goal was not to create
identical animals, but to prove the genetic
material was not lost during cell division.
2. Used sea urchins to do his research.
3. Dreich's experiments involved sea urchins,
which he picked because they have large embryo
cells, and grow independently of their mothers.
Dreich took a 2 celled embryo of a sea urchin and
shook it in a beaker full of sea water until the two
cells separated. Each grew independently, and
formed a separate, whole sea urchin.
B. First cloned mammal and others
1. On July 5, 1996, a lamb was born, cloned from a
frozen mammary cell from another adult sheep.
a. She was generated from a specialized
adult cell, not from an unspecialized
embryonic cell.
b. The cell was then injected into an
unfertilized egg cell which had had its
nucleus removed, and made the cells fuse by
using electrical pulses.
2. Ian Wilmut of the Roslin Institute in Edinburgh,
Scotland, and his colleagues used a cell derived
from the udder of a six-year-old sheep in the final
stage of pregnancy.
a. Dolly took 277 tries to create, and other
labs were unable to reproduce the results.
b. Dolly was the first mammal to be cloned
from an adult cell, rather than an embryo.
3. Other cloned animals
a. The Five Little Pigs from Virginia Tech
b. Tetra: The Monkey
c. Calves in Ishikawa Japan
C. Vocabulary related to cloning.
1. Somatic cell: A somatic cell is generally taken to
mean any cell forming the body of an organism.
Somatic cells, by definition, are not germline cells.
2. Cloning: Cloning is the process of creating an
identical copy of an original organism or thing.
3. Reproductive cloning: is a technology used to
generate an animal that has the same nuclear DNA
as another currently or previously existing animal.
Dolly was created by reproductive cloning
technology.
4. DNA technology cloning: the transfer of a DNA
fragment of interest from one organism to a self-
replicating genetic element such as a bacterial
plasmid.
5. Therapeutic cloning: also called "embryo
cloning," is the production of human embryos for
use in research. The goal of this process is not to
create cloned human beings, but rather to harvest
stem cells that can be used to study human
development and to treat disease.
6. DNA: a nucleic acid molecule in the form of a
twisted double strand double helix that is the major
component of chromosomes and carries genetic
information. DNA, which is found in all living
organisms except some viruses, reproduces itself
and is the means by which
hereditary characteristics pass from one generation
to the next.
7. ethical - Relating to or involving questions of
right and wrong.
8. genes- The building blocks of DNA, which serve
as transmitters of hereditary characteristics
II. Understanding the science of cloning
A. Reproductive Cloning
1. Reproductive cloning: is a technology used to
generate an animal that has the same nuclear DNA
as another currently or previously existing animal.
Dolly was created by reproductive cloning
technology.
a. Isolate the donor cell
b. Remove and discard the nucleus from the
egg cell
c. Transfer the somatic nucleus into the
enucleated egg cell
d. Stimulate cell division
e. Implant the embryo
f. Evaluate final product
III. How does Biotechnology and cloning relate?
A. What is Biotechnology
1. The manipulation (as through genetic
engineering) of living organisms
or their components to produce useful usually
commercial products (as pest resistant crops,
new bacterial strains, or novel
pharmaceuticals);
also : any of various applications of biological
science used in such manipulation
2. Biotechnology crops can be engineered
to tolerate specific herbicides, which make
weed control simpler and more efficient
(United States Department of Agriculture).
Biotechnology can possibly reduce world
hunger and disease by improving local
productivity and by adapting crops to local
climates and soils.
3. Biotechnology makes plants more nutritious by
creating plants with higher vitamin and protein
content and making produce more affordable on the
world market (Freeman Dyson)
4. Norman Borlaug won the Nobel Peace Prize
in 1970 for his work in developing high yield
wheat and other grains in India and other
Third World nations. His work resulted in a
major increase of food production worldwide
in the early 1970’s (James D. Torr). His work
resulted in a major increase of food production
worldwide in the early 1970’s.
G. HOOK:
(DESCRIBE HOW
YOU WILL GRAB
STUDENTS’
ATTENTION AT THE
BEGINNING OF THE
LESSON. BE
CREATIVE.)
Students will complete a KWL chart (chart will be on the board)
by discussing openly what they know about cloning, and what they
want to know. At the end of the lesson, they will complete the
“Learned” section of the chart.
Cloning 101
Introduction to Cloning: A 3 minute video on cloning. After video,
students will be given steps to cloning cards to see if they are able
to organize them in the correct sequence.
http://www.youtube.com/watch?v=gPxH3O5CT-8
Teacher will say: Let’s reflect back to the Point to Ponder, which
says: “Cloning could be considered one of the greatest discoveries
of all time!” After watching the video, what are your thoughts on
cloning? Can it be beneficial to society? (3 minutes)
H. INSTRUCTION:
(TELL, STEP-BY-
STEP, WHAT YOU
WILL DO.)
With the use of the SmartBoard, students will participate in an
Interactive PowerPoint Game: Haven’t I seen You Before or Is it
Simply Multiplicity Part I? This will be implemented to allow
learners to observe connection between cloned animals and
animals that are not cloned.
Teachers will introduce vocabulary words by providing students
with a list of vocabulary words and their definitions. Next, using
the SmartBoard, teachers will show illustrations that relate to each
vocabulary word. Then, students will be provided with vocabulary
cards (only the vocabulary words will appear) that relate to the
pictures.
The teacher will say: “You will find vocabulary words in your
“small basket”. As each picture is shown choose the word that
correlates with the picture and place on it on the picture.” Note:
Each student will have their vocabulary words in a “small basket”
to place on the illustration.
The teachers will then use an (on SmartBoard) interactive
PowerPoint to access whether or not students have mastered
vocabulary.
To introduce Hans Adolf Eduard Driesch the teachers will show a
picture of him and a picture of Dolly on separate sheets if chart
paper. Teachers will divide the students into groups of two. Each
group will receive chart paper with pictures of Hans Adolf Eduard
Driesch and Dolly. Each group will be presented with an envelope.
Inside the envelope, the students will have slips of information
related to both Driesch and Dolly. The students will then (with
removable Scotch Tape) tape each slips of information in the
correct column, either on Driesch or Dolly. Once the students have
placed all the slips, the groups will check with each other to see if
they have the slips in the correct column.
The teacher will say: Now class, we are going to be scientist
today and with all you have learned, you will now clone a mouse.
Students will then create and clone their own mouse through an
interactive simulation.
http://learn.genetics.utah.edu/content/tech/cloning/clickandclone/
Students will imagine not having any food for days and then
presented with the question, “What would you do?”
Teachers will show PowerPoint entitled: Biotechnology.
Teacher will say: Next, we are going to watch a video (from
www.brainpop.com Entitled: Fighting Hunger) that discusses the
shortage of food. During the next few days, you will decide
whether or not farmers should use cloning methods to increase
food production. As you watch this video, begin to think about
your opinions and views as it relates to cloning and using it to
reduce world hunger.
Teachers will guide the students in completing the “L” in the
KWL chart. Students will write on the board anything new that
they learned during the lesson.

H. INSTRUCTION:
(TELL, STEP-BY-STEP,
WHAT YOU WILL DO.)
The teacher will instruct the students to observe the comic
strip shown on the projector.
The teacher will say: Do you believe identical twins share
the same DNA?
Then students will interact with a PowerPoint titled:
“Haven’t I seen you before or is it just multiplicity II”.
Teacher will say: Many of you are already familiar with
understanding the basics of DNA. Have you ever considered
the benefits of using DNA to help society? Let’s watch this
short video that points out a few ways that DNA can serve
as a benefit to society.
4 minutes and 20sec. video on DNA entitled: “The Body’s
Blueprint” from www.brainpop.com (followed by an
interactive quiz)
After the video, the teacher will say: What was mentioned in
the video that related to DNA being used to help society?
The teacher will say (if not mentioned by the students): Yes,
DNA can be used to solve crimes, and increase food
productivity.
Teachers will discuss with students “lab” rules before
starting Strawberry Extraction. Lab rules will include the
following:
Always... Never...
Wear a Buttoned Up Lab
Coat
Eat or Drink in the Laboratory
Wear Gloves if Necessary Touch, Sniff or Taste
Chemicals
Be Aware of the Risks and
Hazards Involved in Any
Experiment
Clean Up at the End
To understand the make-up of DNA, students will be guided
by the teacher in completing a hands-on activity entitled,
“Strawberry DNA Extraction”.
The Teacher will say: This next activity involves extracting
DNA from a strawberry. DNA can be used to reproduce
plants. As you are being guided in this procedure, keep in
mind your final product and whether or not you support
cloning to increase food production to reduce hunger.
The teacher will demonstrate each step with students and
students will follow along:
Step 1: Place one strawberry in a zip lock baggie and
carefully press out all of the air and seal the bag.
Step 2: Smash the strawberry with your fist for 2 minutes.
Step 3: Add 10 ml extraction buffer to the bag and carefully
press out all of the air and seal the bag.
Step 4: Mush again for one minute.
Step 5: Filter through cheesecloth in a funnel into beaker.
Support the test tube in a test tube rack.
Step 6: Discard the extra mashed strawberry.
Step 7: Pour filtrate into test tube so that it is 1/8 full.
Step 8: Slowly pour the ice-cold alcohol into the tube until
the tube is half full and forms a layer over the top of the
strawberry extract.
Teacher will say: At the interface, you will see the DNA
precipitate out of solution and float to the top. You may
spool the DNA on your glass rod or pipette tip.
Step 9: Spool the DNA by dipping a pipette tip or glass rod
into the tube right where the extract layer & alcohol are in
contact with each other. With your tube at eye level, twirl
the rod & watch as DNA strands collect.
A call interview will be conducted with Katrin Hinrichs
DVM, PhD. She is a professor and Patsy Link Chair in
Mare Reproductive Studies Department of Physiology and
Pharmacology College of Veterinary Medicine and
Biomedical Sciences at Texas A&M University. Dr.
Hinrichs led the cloning team on the project of cloning
America's first cloned horse. Students will be provided with
an opportunity to ask questions related to cloning. Dr.
Hinrichs will also discuss her experience with cloning the
first horse.
The teachers will use a Movie Maker tutorial handout to
guide students in creating a “practice” movie. The teachers
will provide students with pictures, but will also guide them
in finding and saving their own.
The teacher says: Now that you have learned some new
information related to cloning, we would like for you to
begin to think about whether or not cloning could be used to
reduce world hunger. Over the next few days, using Movie
Maker, you will create a movie that supports your argument
to present to farmers. The goal is to convince farmers to
donate a portion of their crops or produce to organizations
that support reducing hunger. If you support cloning of
animals, you would suggest cloning to increase the food
supply. If your choice is to avoid cloning, you would
suggest to the farmers to generate additional crops and
produce to donate to organizations worldwide in an effort to
reduce hunger.
The Teacher will say: Now, we will learn some basic
concepts of the program, “Movie Maker”. Please follow
with me by looking at the SmartBoard.
Step 1: Create a new folder on your USB Flash Drive and
name it “mmproject”.
Step 2: Locate and save at least 10 pictures that you believe
relates to cloning or how you may feel about cloning and
save them to your “mmproject” folder that you created on
your USB Flash Drive.
Step 3: Open Windows Movie Maker
-> Start -> Programs -> Movie
Maker
Step 4: Select File -> Save Project As and name your movie
file “movie_CLONE”. Make sure and navigate to your USB
Flash Drive and save this file in the “mmproject” folder you
created.
***Don’t forget to SAVE your movie project often. You
can do this by clicking on File ->Save Project or by simply
clicking on the Floppy Disk icon on the top toolbar (see
illustrations).
Step 5: Click on the Import Pictures link on the left side of
the window (see illustration).
Step 6: With the Import File window open, navigate to your
“mmproject” folder and import each of your pictures into
your Collections.
*Shortcut Tip: Click and select the first picture in the folder;
then hold down the shift-key and click on the last picture in
the folder. This should highlight all of the picture files
between the two files you clicked on. Click Import and all
of the files should move over at the same time into your
Collections.
Step 7: Click and drag each of your pictures (one at a time)
to the Video Timeline at the bottom of your window.
The default setting for each picture is 5 seconds within the
timeline. I suggest keeping it where it is for this project
because when you add transitions and/or effects later
between each picture it will decrease the time each picture is
shown.
Step 8: Once all of your pictures are added to the video
timeline, it is now time to insert some Video Transitions
between the photos.
Click on the drop-down window near the top of your screen
and select Video Transitions from the menu (see
illustration).

his produce to reduce world hunger. If they support cloning
of animals, they would suggest to Mr. Hunter to use cloning
to increase the food supply. If their choice is to avoid
cloning, they would suggest generating additional crops and
produce to donate to organizations worldwide in an effort to
reduce hunger.
Followed by presentations, students and Mr. Hunter will
have open an discussion about their final products.
Vocabulary Sheet Somatic cell — A somatic cell is generally taken to mean any cell forming the body of
an organism. Somatic cells, by definition, are not germline cells.
Cloning — Cloning is the process of creating an identical copy of an original organism or
thing.
Reproductive cloning: is a technology used to generate an animal that has the same
nuclear DNA as another currently or previously existing animal. Dolly was created by
reproductive cloning technology.
DNA technology cloning: the transfer of a DNA fragment of interest from one
organism to a self-replicating genetic element such as a bacterial plasmid.
Therapeutic cloning: also called "embryo cloning," is the production of human embryos
for use in research. The goal of this process is not to create cloned human beings, but
rather to harvest stem cells that can be used to study human development and to
treat disease.
DNA-- a nucleic acid molecule in the form of a twisted double strand double helix that
is the major component of chromosomes and carries genetic information. DNA, which is
found in all living organisms except some viruses, reproduces itself and is the means by
which hereditary characteristics pass from one generation to the next.
Progenitor: A direct ancestor
ethical - Relating to or involving questions of right and wrong.
genes- The building blocks of DNA, which serve as transmitters of hereditary
characteristics.
biotechnology: the manipulation (as through genetic engineering) of living organisms or
their components to produce useful usually commercial products (as pest resistant
crops, new bacterial strains, or novel pharmaceuticals); also : any of various applications of biological science used in such manipulation
chromosomes: rod-shaped structure in a cell. It carries genes, which contain the codes
for features or traits.

Experimented with
cloning sea urchin
cells
Was a German
biologist and
philosopher
Born in Bad
Kreuznach,
Germany
Was created as a
result of the work
by biologist Ian
Wilmut
*Cloned Dolly
Was born in 1892
Original code-
named "6LL3"
Was cloned in 1996
Cloned the first
animal in the
1880’s
It took 277
attempts before a
successfully
cloning……..
Experimented by taking a sea urchin embryo at the
two-cell stage, putting it in a jar with salt waters,
and shook it up. The embryo had split into two. The
two cells developed normally and came out to be
two smaller then normal sea urchins but everything
else was normal.
While experimenting expected each cell to develop
into the corresponding half of the animal to which
it has been destined or preprogrammed, but
instead found that each developed into a complete
sea urchin.
Was cloned at the Roslin
Institute in Midlothian,
Scotland
29 early embryos developed and were
implanted into 13 surrogate mothers
before a successful a clone was
created.
*Cloned the first
mammal
First mammal to be
cloned from an
adult cell, rather
than an embryo
Took two embryos
and fused them
together to form
one embryo.
Took the sea urchins at the 8-cell
stage and flattened them between
two pieces of glass, until the 16-cell
stage and then took off the glass. A
sea urchin developed without defects.
Was produced when scientists used
the nucleus of an cell from a six-
year-old Finn Dorset white sheep.
Raised from the nucleus
of a 6-year old sheep.
Was euthanized on 14
February 2003, aged six
and a half.

Strawberry DNA
Extraction
Introduction:
DNA is found in cells from Animals and Plants. DNA is a
double stranded macromolecule composed of nucleotide bases
pairing Adenine with Thymine and Guanine with Cytosine.
DNA can be extracted from cells by a simple technique with
household chemicals, enabling students to see strands of DNA
with the naked eye.
Purpose:
To extract DNA from the fruit of a strawberry plant
Safety Precautions:
Do not eat or drink in the laboratory.
Wear Apron & Safety Goggles.
Materials / Equipment (per student group):
1. heavy duty zip-lock baggie
2. 1 strawberry (fresh or frozen and thawed)
3. cheesecloth
4. funnel
5. 100 ml beaker
6. test tube
7. wooden coffee stirrer
8. DNA Extraction Buffer (One liter: mix 100 ml of
shampoo (without conditioner), 15 g NaCl, 900 ml water
OR 50 ml liquid dishwashing detergent, 15 g NaCl and
950 ml water)
9. Ice-cold 95% ethanol or 95% isopropyl alcohol
Procedure:
1. Place one strawberry in a zip lock baggie and carefully
press out all of the air and seal the bag.
2. Smash the strawberry with your fist for 2 minutes.
3. Add 10 ml extraction buffer to the bag and carefully
press out all of the air and seal the bag.
4. Mush again for one minute.
5. Filter through cheesecloth in a funnel into beaker.
Support the test tube in a test tube rack.
6. Discard the extra mashed strawberry.
7. Pour filtrate into test tube so that it is 1/8 full.
8. Slowly pour the ice-cold alcohol into the tube until the
tube is half full and forms a layer over the top of the
strawberry extract.
9. At the interface, you will see the DNA precipitate out
of solution and float to the top. You may spool the DNA
on your glass rod or pipette tip.
10. Spool the DNA by dipping a pipette tip or glass rod
into the tube right where the extract layer & alcohol are
in contact with each other. With your tube at eye level,
twirl the rod & watch as DNA strands collect.
Prelab:
Take a look at the sketch of the plant cell below. The
chromosomes (which are made of DNA) are in the nucleus.
This is the only place where DNA is located.
Now match the procedure with what it is doing to help isolate the DNA
from the other materials in the cell.
_____1. Break open the cell A. Squish the fruit to a slush
_____2. Dissolve cell membranes B. Filter your extract through
cheesecloth
_____3. Precipitate the DNA
(clump the DNA together
C. Mix in a detergent solution
_____4. Separate organelles,
broken cell wall, and membranes
from proteins, carbohydrates, and
DNA
D. Layer cold alcohol over the
extract

What is a storyboard?
A story board is a set of panels on which sequential sketches are arranged to show the
important changes of scenes and action in a group of shots.
Why You Need to Create a Storyboard:
Storyboards:
allow you to brainstorm ideas
help you to see what the finished product should look like
help you to more efficiently plan your ideas
make it easier for you to plan how and what to edit for your video
cut down on editing time
help all members of the group to know exactly where they are during the production
process
help you to avoid missed opportunities for camera shots that you could have made
Storyboards should include notes about:
the approximate time for each scene
who will appear in each scene
transitions between scenes
frame size/camera angles
special effects (e.g., lighting)
music
dialogue/narration
When planning your video consider:
your audience
your message
how you will deliver your message (e.g., frame size/camera angles)
o close-ups—show details, expressions/emotions
o medium-range shots—usually involve one or two people at fairly close range;
used to show interaction
o long shots—used to set the scene and let the audience know where the action is
taking place
o shooting from above—makes subject seem small or weak
o shooting from below/looking up—makes subject seem dominant
o shooting from behind—helps audience to see things as subject might see them
