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

B 19

A 11

B 19

C 38

D 76

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

Transcription:

DNA mRNA

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

to replication.

Base pairing rules: A=T, G=C

One of the functions of the skeletal system is to produce red

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

A Muscular System

B Respiratory 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

Which body system is directly responsible for delivering

nutrients to cells throughout the body?

A Circulatory system

B Integumentary system

C Endocrine system

D Respiratory system

Nutrients, as well as oxygen, are

circulated throughout the body by this

system.
