WebThe other main phase of the cell cycle here is where you have active cell division, and it's called mitosis. Mitosis, or sometimes it's abbreviated with just an "M." Mitosis is the time where you have active cell division. Now, there are a few other phases that occur within interphase. The first part of interphase is a growth phase. WebApr 8, 2024 · DNA synthesis occurs during interphase. Complete step-by-step answer: The cell cycle of animal cells has two main stages: the Interphase and M phase. Interphase is the preparatory phase that is further divided into Gap1 (G1) phase, Synthesis (S) phase, and Gap2 (G2) phase. M phase is the mitotic phase where true cell division occurs.
