In the given diagram of cell cycle, the sub-phase of interphase in which DNA replication occurs is labelled as:

Correct answer: B. Option B

  • A. Option A
  • B. Option B
  • C. Option C
  • D. Option D

Explanation

B represents S phase during which DNA replicates.So option B is correct option. A represents G1 phase, C represents G2 phase and D represents M phase. So these options are incorrect as DNA replication doesn't occur here.

About Chromosomes

Chromosomes are DNA-protein structures that carry genes and become visible during cell division. Coverage includes chromatin, centromeres, sister chromatids, homologous chromosomes, chromosome number, and the distinction between diploid and haploid cells, with links to DNA replication, mitosis and meiosis.
