Solution

The correct option is D DNA synthesis
During G $_{1}$ phase, the cell grows in size and synthesizes mRNA and proteins (Known as histones) that are required for DNA synthesis. Once the required proteins and growth are complete, the cell enters the next phase of the cell cycle, S phase. So, the correct answer is option D.
