DNA is replicated at which stage of the cell cycle?
Correct answer: C. S
- A. G0
- B. G1
- C. S
- D. G2
Explanation
DNA is replicated during the S phase of the cell cycle. The cell cycle consists of several phases: interphase (G1, S, and G2 phases) and mitosis (M phase). During the S phase, DNA replication occurs. This is when the cell duplicates its entire genome, ensuring that each daughter cell receives an identical copy of the genetic material. After DNA replication in the S phase, the cell proceeds to the G2 phase, where it prepares for cell division.
