Replication of chromosomal $DNA$

Vedclass · Answer

(D) The $S$ phase (Synthesis phase) is a period in the cell cycle that occurs during interphase,between the $G_1$ phase and the $G_2$ phase.During this phase,the cell replicates its nuclear $DNA$.If the initial amount of $DNA$ in the cell is denoted as $2C$,then after the $S$ phase,the amount of $DNA$ becomes $4C$.However,there is no change in the chromosome number; if the cell had $2n$ chromosomes at the beginning,it remains $2n$ at the end of the $S$ phase.Therefore,the primary characteristic of the $S$ phase is the replication of chromosomal $DNA$.

Which of the following is a characteristic of the $S$ phase?
