Cell Cycle Checkpoints Check In

A new cell goes through the stages of the cell cycle in this order:

First ​ ​ (a)   Second ​ (b)   Third ​ ​ (c)   Fourth ​ (d)   Fifth ​ (e)  

• Interphase G1
• Interphase Synthesis
• Interphase G2
• Nuclear Division during Mitosis
• Cell Division during Cytokinesis

How would the amount of DNA in a cell in G1 compare to that same cell during G2?

• In G2 the amount of DNA would be half of what it is in G1.

• In G2 the amount of DNA would be double what it is in G1.

• In G1 the amount of DNA would be double what it is in G2.

• The amount of DNA would be the same in G1 compared to G2.

In a healthy cell, if a cell cycle checkpoint is NOT met, what is a likely outcome for the cell?

• It will continue to replicate uncontrollably.

• It will continue to grow and proceed to the next stage of the cell cycle.

• It will try to correct the error or undergo apoptosis.

• It will mutate.

Reorder the following events of the cell cycle.

• Cell passes checkpoint and replicates its DNA.

• Cell grows and does its job for the organism.

• Cell continues to grow and make additional organelles.

• Replicated chromosomes are lined up then split apart.

• 2 new nuclei form and the cell divides into 2.

Normally proto-oncogenes are genes that encourage cell division. Mutated proto-oncogenes are called ​ (a)   and they ​ ​ (b)   .

• oncogenes
• overstimulate the cell making it divide a lot
• tumor suppressor genes
• stop cell division
• slow down cell division

Normally tumor suppressor genes stop a cell from dividing. Mutated tumor suppressor genes ​ (a)   .

• don't stop cell division even when they should
• cause the cell to go through apoptosis
• fix mutations in the cell's DNA
• stop the cell from dividing anymore
