Explain how age relates to cancer?

Pitanje 2
2.

Explain how height relates to cancer?

Pitanje 3
3.

State two differences between normal and cancer cells.

Pitanje 4
4.

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

Pitanje 5
5.

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

Pitanje 6
6.

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

Pitanje 7
7.

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

Pitanje 8
8.

The stage of interphase with the definition

  • Cell grows in size

  • Cell checks to make sure the DNA replicated correctly and cell has the proper supplies

  • DNA replicates

  • G2

  • G1

  • S

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?

Pitanje 10
10.

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?

Pitanje 11

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

Pitanje 12
12.

As cell division increases the rate of mutation

The base pair C pairs with during DNA replication.

Pitanje 16
16.

DNA replication results in two DNA molecules

Pitanje 17
17.

When does DNA replication occur?

Pitanje 18

A mistake in the DNA sequence is called

Pitanje 19

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

Pitanje 20
20.

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 to produce the p53 protein.

Pitanje 21

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

Pitanje 22

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

Pitanje 23
