Detailed explanation-1: -S phase is the period during which DNA replication occurs.
Detailed explanation-2: -DNA replication occurs in the nucleus in eukaryotes, whereas in cytoplasm in prokaryotes.
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.
Detailed explanation-4: -S phase of the Interphase is referred to as the synthesis phase. In this phase, DNA replication takes place for the duplication of entire genetic material. During mitosis, DNA replication occurs in the S-phase of the Interphase.
