Vedclass · Answer

(A) The cell cycle is regulated by specific control points known as checkpoints. The most critical checkpoint,often referred to as the 'restriction point' or 'start',occurs at the $G_1 \rightarrow S$ transition. At this stage,the cell commits to $DNA$ replication and division based on internal and external signals. Another significant checkpoint exists at the $G_2 \rightarrow M$ transition,which ensures that $DNA$ replication is complete and accurate before the cell enters mitosis.
