When during the cell cycle is a cell's DNA replicated?
Correct answer: C. S phase
- A. G1 phase
- B. G2 phase
- C. S phase
- D. M phase
Explanation
the S-phase (synthesis phase) during which the DNA is synthesized and (chromosome are replicated) The S phase, or synthesis phase, is a crucial stage of the cell cycle where DNA replication occurs. During this phase, the cell synthesizes an identical copy of its entire genome, ensuring that each daughter cell receives a complete set of genetic information. This process is essential for cell growth and proliferation, as it ensures that daughter cells have the necessary genetic material to carry out their functions and replicate further.
