Briefly summarize the four phases of mitosis and cytokinesis

What will be an ideal response?


Prophase: Chromosomes become visible as threadlike structures. As they continue to condense, they are seen as double structures, with sister chromatids joined at a single centromere.
Metaphase: Chromosomes become aligned at equator of cell.
Anaphase: Centromeres divide, and chromosomes move toward opposite poles.
Telophase: Chromosomes decondense; nuclear membrane forms.

Cytokinesis--Cleavage furrow gradually tightens and the cell eventually divides in two, distributing organelles to the daughter cells.
