WebThe cell cycle describes an orderly sequence of events that are highly regulated. In eukaryotes, the cell cycle consists of a long preparatory period (interphase) followed by mitosis and cytokinesis. Interphase is divided into three phases: Gap 1 (G 1 ), DNA synthesis (S), and Gap 2 (G 2 ). WebMay 18, 2024 · The series of stages that a cell undergoes while progressing to division is known as cell cycle . Cells undergoing division are also termed competent cells. When a cell is not progressing to mitosis, it remains in phase G0 ("G" zero). Therefore, the cell cycle is divided into two major phases: interphase and mitosis. rabbs bowling alley
