Which phase corresponds to the interval between mitosis and initiation of DNA replication?

Options

A. Gap `1//G_(1)` phase
B. Gap `2//G_(2)` phase
C. Synthesis/S phase
D. M phase

Answer

To answer the question "Which phase corresponds to the interval between mitosis and initiation of DNA replication?", we need to understand the structure of the cell cycle.

### Step-by-Step Solution:

1. **Understanding the Cell Cycle**:
- The cell cycle consists of several phases, primarily divided into two main parts: the mitotic phase (M phase) and the interphase, which includes the G1, S, and G2 phases.

2. **Identifying the Phases**:
- The M phase (mitotic phase) is where cell division occurs.
- Following the M phase, the cell enters the G1 phase (Gap 1 phase), where it grows and synthesizes proteins necessary for DNA replication.

3. **S Phase**:
- After the G1 phase, the cell enters the S phase (Synthesis phase), where DNA replication occurs.

4. **Conclusion**:
- Therefore, the phase that corresponds to the interval between mitosis (M phase) and the initiation of DNA replication (S phase) is the G1 phase.

### Final Answer:
The phase that corresponds to the interval between mitosis and initiation of DNA replication is the **G1 phase**.
