during what stage do the chromosomes pull apart

February 22, 2026 • 1 min read

Chromosomes pull apart during anaphase of cell division.

Key idea

In mitosis, sister chromatids separate and are pulled toward opposite poles of the cell during anaphase.

This separation begins right after metaphase, when chromosomes had been lined up in the middle of the cell.

Extra note (meiosis)

In meiosis, homologous chromosomes separate in anaphase I, and sister chromatids separate in anaphase II, but in both cases the “pulling apart” stage is called anaphase.
