If a cat has 38 chromosomes in each of its body cells, how
many chromosomes will be in each daughter cell after
mitosis?
A 11

Mitosis results in daughter cells that are identical to the
parent cell so the chromosome number would remain the
same.
Mitochondria are the power plants of the cell,
producing energy.
DNA
Double Helix
I met DNA AT the Grand Canyon!
Read first position base = tells you the row
Read the second position base = tells you the column
Read the third position base = tells you the line
always read DNA and RNA 5' to 3'
The sequence of nitrogen bases provide
instructions for the production of
proteins.
All of the following are found in a DNA molecule except -
A carbon dioxide
B deoxyribose
C nitrogen
D phosphate
All of the following are found in a DNA molecule except -
A carbon dioxide
B deoxyribose
C nitrogen
D phosphateThe main components of DNA are deoxyribose
(sugar), nitrogenous bases, and phosphate
groups
If the template strand of DNA is 5’AGATGCATC3’, the
complimentary strand will be -
A 3’TCTACGTAG5’
B 5’CTACGTAGA3’
C 3’AGATGCATC5’
D 5’AGACGTCTA3’

Base pairing rules:
A=T
G=C
Mutations in DNA molecules can occur when-
A replication of DNA is exact
B a DNA enzyme attaches to an RNA codon
C RNA codons are replaced by DNA nucleotides
D a change occurs in DNA nucleotide bases
Mutations in DNA molecules can occur when-
A replication of DNA is exact
B a DNA enzyme attaches to an RNA codon
C RNA codons are replaced by DNA nucleotides
D a change occurs in DNA nucleotide bases
By definition, a mutation is a "change".
DNA-->mRNA
In RNA, "T" is replaced by "U"
DNA passes information to RNA during the process of -
A transcription
B active transport
C regeneration
D osmosis

The "twisted ladder" of DNA has to uncoil and unzip prior
to replication.

One of the functions of the skeletal system is to produce red
blood cells.
When a person is frightened by a wild animal, some
organ systems immediately become active, while others
are suppressed. Which of these systems is likely to be
suppressed?
A Muscular System
B Respiratory System
C Endocrine System
D Digestive System

C Endocrine System
D Digestive System
Muscular system is needed for
movement.
Respiratory system for breathing.
Endocrine system releases
adrenaline.
Excretory system is responsible for concentrating and emptying waste from
the body. When an animal is thirsty, the brain tells the body to preserve fluids
in many ways. One of those ways is to limit excretion.
Muscles of the jaw help chew food.
Which body system is directly responsible for delivering nutrients
to cells throughout the body?
A Circulatory system
B Integumentary system

D Respiratory system
Nutrients, as well as oxygen, are
circulated throughout the body by this
system.
