Bioengineering REVIEW DAY! Catalyst:

What is gel electrophoresis? What do restriction enzymes do, and what are they used for?

In GATTACA, what were 3 ways people tested the DNA of in-valids and valids?

Write in complete sentences!

Don’t talk during the Catalyst!

Objectives

By the end of today, all SWBAT…

Evaluate the pros and cons of advances in biotechnology

Ace the unit test tomorrowKick Stroh’s butt tomorrow

Bring it back…

Bioengineering uses science and math to design, produce, and change life Bio = life Engineering = using science and math to design, produce, and change machinesGenetic engineeringStem cell researchCloning

What are the implications?

Stem cells are cells that have the possibility to turn into any type of cell (brain, heart, kidney…)

How could we use this to treat diseases?

Issues

Some people have issues with getting stem cells from aborted embryos

However, there is a new technology that is on the horizon…

CLONING

Cloning

Cloning an organism takes 4 steps… 1) Remove nucleus from an egg 2) Remove nucleus from cell that you want to clone

3) Place nucleus in empty egg 4) Give jolt of electricity to make it divide

Cloning

Cloning can be used to produce personalized stem cells.

Cloning can be used to produce sick cells and we can analyze how they get sick.

However, can “we create life just to destroy it?”

Free-Response Questions

Tomorrow, the majority of your questions will be free response questions.

You will be asked to think of one positive consequence and one negative consequence for each situation.

Rubric

4 points Student makes valid statement AND justifies it with logic

2 points Student makes valid statement without justification

0 points Response is blank or irrelevant

What does it mean to justify? What is one positive consequence of

cloning human beings?

Example: We could clone human stem cells. This is

positive because we could use the stem cells to cure diseases, like Alzheimer’s.

4 points!

What does it mean to justify? What is one positive

consequence of cloning human beings?

Example: Cloning would be positive for society because of the stem cells.

2 points!

What does it mean to justify? What is one positive consequence

of cloning human beings?

Example: I wouldn’t have to go to school

anymore.

Let’s judge together…

Mr. Lewis wants to only hire teachers with no genetic diseases. What is one positive consequence?

Example: No teachers would be absent due to

genetic diseases. Since teachers would be at school more, students would learn more.4 points!

Let’s judge together

Mr. Lewis wants to only hire teachers with no genetic diseases. What is one negative consequence?

Example One negative consequence of Mr.

Lewis’ rule is that teachers would be angry.

Let’s judge together

Mr. Lewis wants to only hire teachers with no genetic diseases. What is one negative consequence?

Example One negative consequence is that some people who would be great teachers would be kept out of the classroom.

2 points!

Let’s Judge together

Mr. Lewis wants to only hire teachers with no genetic diseases. What is one negative consequence?

Example Mr. Lewis should not discriminate hiring teachers based off genetics because that’s trifling.

100 years in the future, the NFL decides that it will only draft players with certain genes for athleticism and strong legs.

What is one positive consequence of this?

What is one negative consequence of this?

Some farmers are able to afford to genetically engineer their crops to produce their own pesticides. This way, farmers won’t have to spend money spraying pesticides and the putting chemicals in the soil and groundwater.

Exit Question

A group of scientists figure out how to clone humans and start harvesting stem cells. They decide to clone anyone that asks to be cloned. What is one positive consequence? What is one negative consequence?
