In which stage of cell cycle, DNA replication occurs? (a) G 1 phase (b) Sphase (c) G 2 phase (d) Mphase
Option B During S phase or synthetic phase the replication of DNA takes place. For replication of DNA histone proteins are required so they are also synthesized during this phase. It takes about 30% 50% of the total cell cycle. Prophase and telophase are stages involved in mitosis or meiosis. During G 2 phase division of centrioles, mitochondria and chloroplasts occurs.
