The checkpoint in cell cycle plays important role in

ARepairing DNA damage.
BApoptosis initiation.
CAssessing DNA damage.
Correct Answer
DNone of the above.

Solution

Cell cycle checkpoints act as a control mechanism during cell division in a eukaryotic cell. They are essential to ensure proper cell division. Each point acts like a potential checkpoint where the cell conditions and condition of DNA are assessed and only then the further process takes place. Tere are two checkpoints in a cell division- the G1 and G2 stage.
