What is the purpose of checkpoints in the cell cycle

The purpose of checkpoints in the cell cycle is to ensure that there are no mistakes in the mitotic process.

In other words, checkpoints in cell cycles are a kind of quality control that ensures that the major events of the cycle take place without mistakes.

A typical cell cycle consists of the interphase and the m phase, which is essentially the mitotic division phase. The interphase is further divided into:

There are 3 major checkpoints in a typical cell cycle:

If the checkpoint mechanisms detect problems with the DNA, the cell cycle is halted and the cell attempts to either complete DNA replication or repair the damaged DNA. If the DNA has been correctly replicated, Cyclin dependent Kinases signal the beginning of mitotic cell division.
