Explanation:
Detailed explanation-1: -S phase is the period during which DNA replication occurs.
Detailed explanation-2: -During the S phase of the cell cycle, DNA replication occurs at the interphase. There are four stages in the cell cycle i.e. G1, S, G2, and M. DNA replicates before actual cell division so that identical set of the genome of the parent cell is received by each daughter cell.
Detailed explanation-3: -The interphase of a normal cell cycle will thus, consist of the G1 (Gap 1) phase, S (Synthesis) phase, and G2 (Gap 2) phase. The S phase is the phase in which replication of DNA will take place which is then followed by histones synthesis. This is the phase taking place between the G1 phase and G2 phase.
