Mitosis, Overview

This video presents the same text shown beside it, spoken and on screen. It adds nothing the text does not say.

State

Mitosis, also called karyokinesis, is nuclear division: a process, run in five named stages, that separates a cell's replicated chromosomes into two identical new nuclei.

Show

Mitosis proceeds through prophase, prometaphase, metaphase, anaphase, and telophase, in fixed order, whenever a eukaryotic cell divides its nucleus.

Watch for

Mitosis divides the nucleus only — cytokinesis, a separate process, divides the rest of the cell afterward.
