How many phases are in cell cycle
WebNot all cells adhere to the classic cell-cycle pattern in which a newly formed daughter cell immediately enters interphase, closely followed by the mitotic phase. Cells in the G0 phase are not actively preparing to divide. … Web17 jul. 2024 · There are two stages or phases of meiosis: meiosis I and meiosis II. Before a dividing cell enters meiosis, it undergoes a period of growth called interphase. At the end of the meiotic process, four daughter cells are produced. G1 phase: The period prior to the synthesis of DNA.
