WebG1 phase (gap 1 phase) is the first gap, or growth phase in the cell cycle. For cells that will divide again, G 1 is followed by replication of the DNA, during the S phase. The S phase (synthesis phase) is period during which a cell replicates its DNA. Figure 3.30 Cell Cycle The two major phases of the cell cycle include mitosis (designated M ...
