Question

Preparation phase of mitosis is

• A. G${}_1$ phase
• B. S phase
• C. Prophase
• D. Interphase

Answer 1

The correct option is D Interphase

Preparation phase of mitosis is interphase. During G${}_1$ phase, the cell grows in size and synthesizes mRNA and proteins 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. During G${}_2$ phase again the RNA and protein synthesis continues.
