Transitioning from the G2 phase to the M phase is another critical part of the cell cycle. In G2 phase, the cell continues to grow and prepares for mitosis, the process where the cell divides. This transition ensures that the cell is ready for division, with all DNA properly replicated and repaired if needed.
- Cyclin A and CDK2 are important during the S and early G2 phases.
- As the cell approaches mitosis, cyclin B teams up with CDK1.
These complexes check and balance the cell cycle’s progress, regulating when the cell can safely enter mitosis. This ensures that division occurs smoothly, without errors.
