1)Describe what takes place in the three phase of interphase.
2) what are cell cycle checkpoints? Where are they found in the cell cycle? What do they check for?
Describe the cell cycle overall (not each phase). What is interphase, what are the G phases, and what is S phase?
Briefly explain: What is meant by the term “cycle” in cell cycle? What is happening in the S phase and M phase?
