What is the overall purpose of the cell cycle checkpoints?.
Red blood cells have a tough job, circulating through our bodies rapidly to transport oxygen and carbon dioxide. Because of their job, they are worn out quickly, yet we need healthy functional red blood cells all the time. How does our body accommodate that need? (1/2 pts)

7. Answer the following questions about the cell cycle checkpoints: (2 pts) a. In the cell cycle, where are the three checkpoints?
b. What does each checkpoint “check” for?
c. What is the overall purpose of the cell cycle checkpoints?
d. What happens when a cell no longer responds to these checkpoints?
8. Where do cancer cells differ in their cell cycle from normal cells? (1/2 pts)
9. Most adults survive chemotherapy, but unborn children frequently do not. Why do you think that is? Specifically, what is the difference between an adult and an unborn child that would account for this difference? (1/2 pts)
