(B) During the $S$ (synthesis) phase of interphase,$DNA$ replication occurs,resulting in the doubling of the $DNA$ content within the nucleus.After the $S$ phase,the cell enters the $G_2$ phase.Since the $DNA$ has already replicated,each chromosome consists of two sister chromatids,meaning there are two $DNA$ molecules per chromosome in the $G_2$ phase.

The number of $DNA$ molecules in a chromosome at the $G_2$ stage of the cell cycle is:
