`G_(2)` phase occurs between

Options

A. `G_(1)` and S
B. M and S
C. S and M
D. `G_(1)` and M

Answer

To answer the question "G2 phase occurs between," we need to understand the structure of the cell cycle. Here’s a step-by-step solution:

### Step-by-Step Solution:

1. **Understanding the Cell Cycle**: The cell cycle consists of several phases that a cell goes through as it grows and divides. The main phases are Interphase and the Mitotic phase (M phase).

2. **Identifying Interphase**: Interphase is divided into three sub-phases: G1 (Gap 1), S (Synthesis), and G2 (Gap 2).

3. **Sequence of Phases**:
- The G1 phase is the first phase where the cell grows and prepares for DNA replication.
- The S phase follows, during which DNA replication occurs, doubling the genetic material.
- After the S phase, the G2 phase occurs, where the cell continues to grow and prepares for mitosis.

4. **Transition to Mitosis**: After the G2 phase, the cell enters the M phase, which is the phase of mitosis where the cell divides.

5. **Conclusion**: Therefore, the G2 phase occurs between the S phase and the M phase.

### Final Answer:
The G2 phase occurs between the S phase and the M phase.
