WebIn the S phase (synthesis phase), DNA replication results in the formation of two identical copies of each chromosome—sister chromatids—that are firmly attached at the centromere region. At this stage, each chromosome is made of two sister chromatids and is a duplicated chromosome. The centrosome is duplicated during the S phase. WebCorrect option is C) G 2 phase comes after S phase. In S phase synthesis of DNA occurs. The amount of DNA doubles but the chromosome number or diploid content of the cell remains the same.
