A cell grows and carries out all normal metabolic functions and processes in a period called G 1 (Figure 2.5. 1 ). G1 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 …

WebThe duration of the cell cycle varies from organism to organism and from cell to cell. Certain fly embryos sport cell cycles that last only 8 minutes per cycle! Some mammals take much longer than that--up to a year in certain liver cells. Generally, however, for fast-dividing mammalian cells, the length of the cycle is approximately 24 hours.
