The stage of cell cycle when cell decides to undergone differentiation is

Options

A. `G_(0)`
B. `G_(1)`
C. `G_(3)`
D. `G_(4)`

Answer

**Step-by-Step Solution:**

1. **Understanding the Cell Cycle**: The cell cycle consists of several stages, including interphase (G1, S, G2) and the mitotic phase (M phase). Interphase is where the cell grows and prepares for division.

2. **Identifying the Stages**:
- G1 phase: The first growth phase where the cell grows and prepares for DNA synthesis.
- S phase: The synthesis phase where DNA replication occurs.
- G2 phase: The second growth phase where the cell continues to grow and prepares for mitosis.
- G0 phase: A resting phase where the cell is not actively preparing to divide.

3. **Differentiation Process**: Differentiation is the process by which a cell becomes specialized for a specific function. This often occurs when a cell exits the cell cycle and enters a resting state.

4. **Determining the Correct Phase**: The question asks for the stage of the cell cycle when a cell decides to undergo differentiation. This decision typically occurs in the G0 phase, where the cell has exited the active cycle and is no longer preparing to divide.

5. **Conclusion**: Therefore, the stage of the cell cycle when a cell decides to undergo differentiation is the **G0 phase**.
