Introduction. Chromosomal DNA replication occurs during a phase of the cell cycle known as the S phase. Although the length of the S phase can vary significantly between different cell types, several absolute controls exist that dictate when and how many times in a cell cycle DNA replication can occur.
S-phase (synthesis phase) is the part of the cell cycle in which DNA is replicated, occurring between G1 phase and G2 phase.Precise and accurate DNA replication is necessary to prevent genetic abnormalities which often lead to cell death or disease.-phase (synthesis phase) is the part of the cell cycle in which DNA is replicated, occurring between G1 phase and G2 phase.
