Mitosis
Mitosis
Eukaryotic nuclear division that separates replicated chromosomes into two daughter nuclei.
Overview
EXPLORE BY LEVELNuclear division that separates replicated chromosomes into daughter nuclei, usually preserving the chromosome-set number. is the part of cell division that sorts copied DNA molecules packaged with proteins. Each replicated chromosome is counted as one until its sister chromatids separate. so each new nucleus gets a matching set. It usually works with cell splitting to make two daughter cells.

Mitosis preserves chromosome complement through regulated kinetochore–microtubule attachment, spindle-checkpoint signaling, cohesin cleavage, and coordinated cytokinesis. Outcomes can vary in specialized or abnormal divisions.
