- G1: The cell grows and duplicates its contents (except the chromosomes).
- S: The cell duplicates its chromosomes
- G2: The cell checks for error in the duplicated chromosomes
Mitosis
- Prophase: the cell's chromosomes become visible, and nuclear membranes begin to dissolve. Also, centrioles migrate to opposite poles of the cell, and spindle fibres begin to form between the two centrioles.
- Metaphase: The chromotids move to the center of the cell, and form the metaphase plate.
- Anaphase: The centromere splits apart, and the chromotids move to the opposing poles of the cell.
- Telophase: nuclear membrane begins to reappear. Chromosomes begin to uncoil. The spindle fibres begin to disappear
Cytokinesis:
- The two daughter cells separate
