Vedclass · Answer

(D) The cell cycle consists of two main phases: Interphase and $M$ phase (Mitosis).Interphase is divided into three sub-phases: $G_1$ phase,$S$ phase,and $G_2$ phase.Statement $P$ is incorrect because the $G_1$ phase is the first phase of interphase,not the final one. The final phase of interphase is the $G_2$ phase.Statement $Q$ is incorrect because $DNA$ synthesis (replication) occurs during the $S$ phase (Synthesis phase),not the $G_2$ phase.Therefore,both statements $P$ and $Q$ are incorrect.

Statement $P$: The $G_1$ phase is the final phase of interphase.
Statement $Q$: $DNA$ synthesis occurs in the $G_2$ phase.
