Vedclass · Answer

(C) In the cell cycle,the $G_1$ phase is the first gap phase where the cell grows and prepares for $DNA$ replication,but $DNA$ replication (chromosome replication) occurs during the $S$ phase (Synthesis phase).Therefore,Statement $A$ is incorrect.After the $S$ phase,the cell enters the $G_2$ phase,where it prepares for mitosis. After completing the $G_2$ phase,the cell enters the $M$ phase (Mitosis).Therefore,Statement $B$ is correct.Thus,Statement $A$ is incorrect and Statement $B$ is correct.

Statement $A$ - Chromosomes replicate in the $G_1$ phase.
Statement $B$ - The cell enters mitosis from the $G_2$ phase.
