What is the primary purpose of cell cycle checkpoints?
A
To ensure that the cell's DNA is accurately replicated and any damage is repaired before cell division.
B
To permanently halt the cell cycle in all cells to prevent division.
C
To speed up the process of cell division to increase cell proliferation.
D
To initiate apoptosis in all cells that enter the cell cycle.

Understand the concept of the cell cycle: The cell cycle is a series of phases that cells go through to grow and divide. It includes stages such as interphase (G1, S, G2) and mitosis (M phase).
Learn about cell cycle checkpoints: These are control mechanisms in the cell cycle that ensure the accuracy and integrity of cell division. They occur at various points, such as the G1 checkpoint, G2 checkpoint, and the M checkpoint.
Explore the function of checkpoints: The primary purpose of cell cycle checkpoints is to monitor and verify whether the processes at each phase of the cell cycle have been accurately completed before the cell proceeds to the next phase.
Focus on DNA replication and repair: Checkpoints play a crucial role in ensuring that DNA is correctly replicated and any damage is repaired. This prevents the propagation of errors and maintains genomic stability.
Consider the consequences of checkpoint failure: If checkpoints fail, it can lead to uncontrolled cell division, which may result in conditions like cancer. Therefore, checkpoints are vital for maintaining healthy cell proliferation.
