What happens if DNA is not replicated? The DNA replication occurs at the synthesis phase of the cell cycle. If DNA replication does not occur, then the cell cycle will not proceed to the next stage and the subsequent division will not happen.

WebDuring interphase, G1 involves cell growth and protein synthesis, the S phase involves DNA replication and the replication of the centrosome, and G2 involves further growth and protein synthesis. The mitotic phase follows interphase. Mitosis is nuclear division during which duplicated chromosomes are segregated and distributed into daughter nuclei. WebS is the period of DNA synthesis, where cells replicate their chromosomes. G2 is the period between the end of DNA replication and the start of cell division.
