2

Explain how age relates to cancer?

2

Explain how height relates to cancer?

2

State two differences between normal and cancer cells.

2

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.

1

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

1

The stage of the cell cycle where the cell membranes form to divide a cell into two cells

3

The stage of interphase with the definition

DNA replicates
Cell grows in size
Cell checks to make sure the DNA replicated correctly and cell has the proper supplies

S

1

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?

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?

1

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

1

As cell division increases the rate of mutation __________

1

DNA replication results in

1

The base pair C pairs with __________ during DNA replication.

1

The base pair T pairs with __________ during DNA replication.

1

DNA replication results in two DNA molecules

1

When does DNA replication occur?

1

A mistake in the DNA sequence is called

1

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

2

A gene on chromosome 17 codes for the p53 protein.

Select from the drop-down menus to correctly complete the sentence.

After the gene is __________ into mRNA the mRNA is __________ to produce the p53 protein.

2

A student created a model of a DNA sequence and its mRNA transcript, as shown.

DNA 3'- AGC CGT ATC - 5'
RNA  5'- TCG GCA TAG- 3'

Another student found a mistake in the model
Select from the drop-down menus to complete the sentence describing the correction that should be made to the model.

The __________ nucleotides in the mRNA transcript should be replaced with __________ nucleotides

1

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

1

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

1

__________ plays an important role in preventing cancer by telling cells to die when they are damaged. But this process is not always successful.

1

What does transcription produce?

1

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