telophase

Detailed explanation-1: -Metaphase leads to anaphase, during which each chromosome’s sister chromatids separate and move to opposite poles of the cell. Enzymatic breakdown of cohesin-which linked the sister chromatids together during prophase-causes this separation to occur.
Detailed explanation-2: -In anaphase I, the homologous chromosomes are separated. In prometaphase II, microtubules attach to the kinetochores of sister chromatids, and the sister chromatids are arranged at the midpoint of the cells in metaphase II. In anaphase II, the sister chromatids are separated.
Detailed explanation-3: -The sister chromatids are separated simultaneously at their centromeres. The separated chromosomes are then pulled by the spindle to opposite poles of the cell.
