S Phase - an overview ScienceDirect Topics
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. So, if the mother cell has 32 picogram DNA in G 2, this means originally the cell has 16 picogram of DNA. WebFour Solution The correct option is B Two During the S phase of the cell cycle, there is DNA replication (creating a copy of itself).
