Vedclass · Answer

(D) The $S$ phase (Synthesis phase) is a critical stage of interphase in the cell cycle.During this phase,$DNA$ replication occurs,meaning the amount of $DNA$ per cell doubles.If the initial amount of $DNA$ is denoted as $2C$,it increases to $4C$ at the end of the $S$ phase.Additionally,the centrioles in the cytoplasm also duplicate during this phase.Therefore,the replication of $DNA$ and the duplication of chromosomes (in terms of chromatid content) are the defining characteristics of the $S$ phase.
