The correct answer to this question is S phase. The cell cycle is the cycle that allows the growth and division of cells for the purpose of reproduction and repair of cells and tissue. DNA replication occurs during the S phase of the cell cycle. The cell cycle is divided into two parts – the interphase and mitotic phase. Interphase is further divided into G1, G2, and S phase. In interphase, the cell grows, and DNA is replicated before the mitotic phase occurs.

In this phase, materials of DNA are doubled before the cell cycle progresses to mitosis. The S phase is the synthesis phase when DNA is replicated. This phase occurs between G1 and G2 phases. In the mitotic phase, the daughter nuclei are formed by the segregation of the duplicated chromosome. The cytoplasm is also divided to form 2 daughter cells at the end of the cell cycle.
