Vedclass · Answer

(B) In a somatic cell cycle,the cell undergoes interphase and the $M$-phase (mitosis).$1$. The $G_1$ phase is the first gap phase where the cell grows and prepares for replication,but $DNA$ content remains the same as the parent cell.$2$. The $S$ phase (Synthesis phase) is the period where $DNA$ replication occurs,doubling the amount of $DNA$ in the nucleus.$3$. The interphase (comprising $G_1, S, G_2$) is typically much longer than the $M$-phase,which contradicts option $(C)$.Therefore,the correct statement is that $DNA$ replication occurs in the $S$ phase.
