The cell division cycle is a carefully orchestrated series of events that occur in a timely and orderly fashion. The ordering of the cell cycle is necessary to ensure that adequate cell growth (G1 and G2 phases) has occurred prior to DNA synthesis (S phase) and cell division or mitosis (M phase), DNA is replicated faithfully into two duplicate copies (S phase), and the cell divides into two equal daughter cells (M phase).
