The cell cycle is the series of events that a cell goes through as it grows and divides into two daughter cells. The cell cycle is comprised of two main phases: the interphase (G1, S, G2) and the mitotic phase (M). During interphase, the cell grows and replicates its DNA in preparation for division. During the mitotic phase, the replicated chromosomes separate and the cell physically divides into two daughter cells. The cell cycle is a repeating process that allows for growth, DNA repair, and the generation of new cells.
