Which phase of the cell cycle is responsible for DNA replication?

Explanation:
DNA replication happens during the S phase of interphase. In this phase the cell copies its entire genome, producing identical sister chromatids for each chromosome so that, when division occurs, each daughter cell gets a complete set of genetic material. The replication is semi-conservative, meaning each new DNA molecule consists of one old strand and one new strand. The S phase is preceded by G1, where the cell grows and accumulates resources, and followed by G2, where the cell finalizes preparation for division and checks that replication occurred correctly. Mitosis, by contrast, is the process of separating the sister chromatids into two new nuclei, not duplicating DNA.
