Question 21
Keeping in mind the events of each part of the cell cycle, describe where cells might exit the cell cycle to G0. Why did you choose this location? (Hint: Think of a place where the cell functions normally, but isn't preparing to divide.)
Question 22
Consider a cell in G0. Use information from Models 1 & 2 to answer:
a. In order for this cell to divide normally, what would need to occur?
b. What if the phase(s) identified in part (a) did not occur? What would be the outcome?
