Control and Regulation of the Cell Cycle
- The regulation of the cell cycle is important so that faulty or compromised cell could not divide.
- There can be a mutation during DNA replication and other events of the cell cycle.
- Therefore, there are checkpoints in the cell cycle that would check for the errors and would stop the cell cycle if there is any fault and would allow the cell cycle to continue if there is no fault.
- There are three checkpoints in the cell cycle as G1 checkpoint, G2 checkpoint and M checkpoint.
M checkpoint:
- The M checkpoint occurs near the end of the metaphase stage of karyokinesis
- It checks whether all the sister chromatids are correctly attached to the spindle fibres.
-
The M checkpoint occurs near the end of the metaphase stage of karyokinesis.
