Question

The DNA molecules of each chromosome replicates in

• A. G${}_1$ phase
• B. G${}_2$ phase
• C. S phase
• D. Mitotic phase

Answer 1

Answer: (C)

S phase

The interphase is characterized by G${}_1$, S phase and G$-2$ phase. S-phase or the synthesis phase is the part of the cell cycle in which DNA is replicated, occurring between G${}_1$ phase and G${}_2$ phase.

So, the correct answer is option C.
