Question

In which stage of cell cycle, DNA replication occurs?

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

Answer 1

Answer: (B)

S phase

• The interphase is characterized by three major phases, G${}_1$ phase, 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 B.
