telophase, in mitosis and meiosis, the final stage of cell division in which the spindle disappears and the nucleus forms around each set of daughter chromosomes. Preceded by anaphase, telophase is usually followed by cytokinesis, in which the cytoplasm is physically divided to form two daughter cells. In meiosis, telophase I is followed by prophase II.

During telophase, the chromosomes begin to decondense and the now-defunct spindle breaks down. A new nuclear envelope, derived from vesicles of endoplasmic reticulum, surrounds the unraveling chromosomes, and nucleoli re-form. The separation of the two sets of chromosomes is now complete, and the nuclei of the daughter cells enter interphase (the stage, or phase, after the completion of mitosis).
