Interphase
Nuclear membrane present, chromosomes relaxed
Prophase
Chromosomes condense and mitotic spindle forms.
Prometaphase
Nuclear membrane disintegrates, and spindle microtubules anchor to kinetochores.
Metaphase
Chromosomes align on the metaphase plate; spindle-assembly checkpoint.
Anaphase
Sister chromatids separate, becoming individual chromosomes that migrate toward spindle poles.
Telophase
Chromosomes arrive at spindle poles, the nuclear membrane re-forms, and the condensed chromosomes relax.
Cytokinesis
Cytoplasm divides; cell wall forms in plant cells
When does the number of DNA molecules double? When does it get cut in half?
