WebIn a simple manner, the cell cycle is the time that elapses since the cell divides until it re-enters in another mitotic division. The cell cycle is divided into different phases, named G1 (gap phase 1), S (DNA synthesis), G2 (gap phase 2) and M (mitosis/meiosis), eventually resulting in the formation of two daughter cells.
