Cytokinesis begins during anaphase of mitosis and continues through telophase, finishing as the cell enters the next interphase.

Quick Scoop: Core Idea

  • The cell cycle has a mitotic (M) phase that includes mitosis and cytokinesis.
  • Within mitosis, cytokinesis is triggered shortly after sister chromatids start separating in anaphase.
  • The physical division of the cytoplasm then proceeds through telophase and is usually completed by the start of the next interphase.

Where It Fits in the Cell Cycle

  • Cell cycle stages: G1, S, G2 (together called interphase), then M phase (mitosis + cytokinesis).
  • Cytokinesis is part of the M phase but is distinct from nuclear division (mitosis) itself.

So, when asked “in what stage of the cell cycle will cytokinesis begin,” the best answer is: it begins during anaphase of mitosis, within the M phase of the cell cycle.

TL;DR: Cytokinesis begins in anaphase of mitosis (within M phase) and ends by the close of telophase, as the cell enters the next interphase.
