The primary purpose of checkpoints in the cell cycle is to ensure that the cell progresses through each phase of the cycle accurately and without errors. Checkpoints act as regulatory points where the cell evaluates and verifies that specific conditions have been met before proceeding to the next phase. These checkpoints act as quality control mechanisms to prevent damaged or incorrectly replicated DNA from being passed on to daughter cells. If the checkpoints detect abnormalities or errors, they can trigger cell cycle arrest to allow for necessary repairs or initiate cell death if the damage is irreparable. The checkpoints also play a role in coordinating the timing of cell division and ensuring that the cell cycle proceeds in a controlled and orderly manner.
