If a cell has accumulated DNA damage, it is unlikely to A) pass the G₂checkpoint. B) synthesize cyclin- dependent kinases. C) activate DNA repair mechanisms. D) enter G₁from mitosis.

Question

Quizplus · Accepted Answer

When a cell has accumulated DNA damage, it will activate checkpoint pathways that prevent the cell from progressing through the cell cycle until the damage is repaired. The G₂checkpoint is the checkpoint that monitors DNA damage and prevents the cell from entering S phase until the damage is repaired. Therefore, if a cell has accumulated DNA damage, it is unlikely to pass this checkpoint and enter S phase.
