Teaching MPPSC Assistant Professor Mock Test Series 2025 Life Sciences Cellular Organization Cell Division and Cell Cycle
Mitotic cyclin increases gradually through the G2 phase of the cell cycle but the activity of mitotic CDK1 increases suddenly at the onset of M phase. This is because
1
active CDK1 subunit is synthesized in M phase.
2
mitotic cyclin is sequestered in the cytosol.
3
activation of CDK1 requires post-translational modifications.
4
the inhibitor of CDK1 is degraded in the M phase.
