Explain how tumors form using your knowledge of the cell cycle.

1

The stage of the cell cycle where the cell grows in size, replicates DNA, and develops.

cytokinesis

interphase

mitosis

GO

1

The stage of the cell cycle where the chromosomes of the cell separate and two identical cells are made.

People who have leukemia, a cancer that affects white blood cells, are often given Cytarabine. This drug inhibits the synthesis of DNA. Which phase of the cell cycle is most affected by Cytarabine?

G1 phase

S phase

G2 phase

M phase

1

The diagram below represents the cell cycle.
When cells leave the cell cycle, they exit during G1 phase and then enter G0 phase, a resting period. Most normal cells can leave G0 phase and reenter the cell cycle at G1 phase before entering S phase. Cancer cells are different because they cannot enter G0 phase and are likely to do which of the following?

Fail to complete S phase

Mutate during G1 phase

Repeat the cell cycle continuously

Die after completing mitosis

1

Which statement describes what would most likely happen if p53 mutated and could not perform its task?

The cell would regain control of the cell cycle by adding an additional checkpoint at cytokinesis.

The cell would divide without control and produce new cells that make p53 without the mutation.

The cell would regain control of the cell cycle by using a type of lipid instead of p53.

The cell would divide without control and lead to the formation of cancer.

DNA replication results in

a mRNA strand

a protein chain

two DNA strands

two new cells

1

DNA replication results in two DNA molecules

each with two new strands

one with two new strands and the other with two original strands

each with one new strand and one original strand

each with two original strands

1

When does DNA replication occur?

all the time

before cell division

after gametes are formed

whenever it wants

1

A mistake in the DNA sequence is called

transcription

translation

mutation

osmosis

1

The model shows a mutation to a partial sequence of bases in a gene. Which type of mutation does the model represent?

deletion

insertion

substitution

translatocation

2

1

In cancer cells, mutations in the DNA cause the cells to reproduce uncontrollably, forming a tumor. Cancer directly affects which cellular process?

fertilization

mitosis

osmosis

conjunction

1

Which of the following is a primary reason for cancer cells developing in an organism?

Cancer cells are only caused by a genetically inherited gene.

Cancer cells are the result of other pre-existing abnormalities in the body's tissues.

Cancer cells are created by mutations resulting in signals that fail to control normal cell behavior.

Cancer genes are duplicated and spread throughout the body, which affects every cell in the body.

1

What does transcription produce?

DNA

protein

tRNA

mRNA

1

Which of these is the direct result of an error in the transcription of a DNA nucleotide?

The nuclear membrane is ruptured.

Amino acids do not bond to tRNA.

A codon sequence is incorrect.

Transportation of mRNA does not occur.

null

Image W is a molecule that is a double helix. Image W is

protein chain

DNA

mRNA

enzyme

1

Which of the following is the correct sequence of events in the creation of a protein?

Amino Acid--> DNA--> RNA-->Protein

DNA --> RNA --> Amino Acid --> Protein

Protein --> DNA --> RNA --> Amino Acid

DNA --> Protein --> RNA --> Amino Acid
