Stage |
Major Features |
G0 phase |
Stable, nondividing period of variable length. |
Interphase |
|
G1 phase |
Growth and development of the cell; G1/S checkpoint. |
S phase |
Synthesis of DNA. |
G2 phase |
preparation for division; G2/M checkpoint. |
M phase |
|
Prophase |
Chromosomes condense and mitotic spindle forms. |
prometaphase |
Nuclear envelope 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 envelope re-forms, and the condensed chromosomes relax. |
Cytokinesis |
Cytoplasm divides; cell wall forms in plant cells. |
