10.1Q1 Define three stages of the cell cycle? Correct Answer-Interphase 
G0: where cells rest 
G1: where cells grow and expand 
S: where DNA is replicated 
G2: where cells repair damaged DNA and duplicate centrosomes 
 
Cell division (M) phase 
Where cells undergo nuclear and cytoplasmic division 
 
Each stage has checkpoints that check for completion and accuracy of previous step before starting the next one
