Vedclass · Answer

(A) During the $S$-phase (Synthesis phase) of the cell cycle,$DNA$ replication occurs.Although the amount of $DNA$ per cell doubles (from $2C$ to $4C$),the number of chromosomes remains the same.This is because the sister chromatids remain attached at the centromere.If a cell has $2n$ chromosomes at the $G_1$ phase,it will still have $2n$ chromosomes after the $S$-phase.

What would be the change in the chromosome number during $S$-phase?
