Which phase is DNA replicated in mitosis?

DNA replication does not occur during mitosis itself. Instead, it occurs during the S phase of interphase, which precedes mitosis. Mitosis is the process by which the cell’s duplicated chromosomes are segregated into two daughter cells. The DNA replication that takes place in the S phase ensures that, by the time mitosis begins, each chromosome has been replicated, and the genetic material is ready for distribution to the daughter cells.
