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

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?

1

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

1

The arrow labeled X represents a process where DNA is read, copied, and made into a single strand of mRNA. This process called

1

The arrow labeled Y represents the step in the process when mRNA and tRNA work together in the ribosome. This process is called

1

The structure labeled Z is what is created as a result of protein synthesis. Structure Z is a long strand of what

1

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