Webb24 jan. 2024 · Cell Cycle is a series of events in a cell at the time of its growth and division. These events include cell division, in which a parent cell divides into two or more daughter cells. The cell cycle consists of two stages interphase – the beginning of the cell division and the mitotic phase – which is the actual period of cell division.
