The correct option is C S
S-phase (synthesis phase) is the part of the cell cycle in which DNA is replicated. It occurs between G1 phase and G2 phase.
The G1 phase, or Growth 1/Gap 1 phase, is the first of four phases of the cell cycle that takes place in eukaryotic cell division. In this part of interphase, the cell grows in size and synthesizes mRNA and proteins in preparation for subsequent steps leading to mitosis.
G2 phase, or Gap 2 phase, is the second subphase of Interphase in the cell cycle directly preceding mitosis. It follows the successful completion of S phase, during which the cell's DNA is replicated.
Mitosis and cytokinesis together define the mitotic M phase of an animal cell cycle. Here the division of the mother cell into two daughter cells genetically identical to each other takes place.
