WebThe cell cycle consists of four stages: G1, S, G2, and M. G1 and G2 are 'gap' phases in which the cell grows and prepares to divide. S in the synthesis phase in which the chromosomes (DNA) are copied (replicated). M is the mitotic phase in which the cell physically divides into two daughter cells. Most cells are NOT actively dividing. WebDuring the G2 phase of the cell cycle, Cdk1/Cyclin B (also referred to as Cdc2/Cyclin B in Xenopus) complexes accumulate and are held inactive by phosphorylations on Thr14 and Tyr15 of Cdk1.
