<prompt> DNA synthesis takes place in which phase of cell cycle -G1SG2M  <response>: Ans. is bi.e., S Cell cycleo In cell, the replication of the DNA occurs only at a specific time during the life of the cell. This period is referred to as the synthetic phase. The various phases of cell cycle are in sequence G0-G1-S-G2-M. G1 : Presynthetic phaserinterval.S : Synthetic phase DNA synthesis.G2. : Post synthetic phasepremitoic phaseinterval.M : Mitotic phase : Cells are produced which either directly reenter next cycle or pass into non proliferative Go phase.G0 : Quiescent state.
