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.
DNA replication occurs during the S stage of interphase.   Interphase is the stage between two mitotic or meiotic divisions. It can be slpit into three stages:G1, S a â¦ nd G2.   During G1 (gap 1), cells grow and build up ATP on preparation for DNA replication.   During the S (synthesis) phase the DNA is replicated.   During the G2 phase the cell prepares itself for the process of cell division (mitosis or meiosis).   See:   http://www.emc.maricopa.edu/faculty/farabee/BIOBK/BioBookmito.html.
