Mitotic cyclin levels are highest just before which event?
- A
End of cytokinesis
- B
Entry into S phase
- C
Beginning of G1
- Dcheck_circle
Entry into mitosis (G2/M transition)
Explanation
Mitotic cyclin accumulates during G2 and peaks at G2/M, where it binds CDK1 to form MPF and trigger entry into mitosis. It is then degraded during anaphase.
