Non-dividing cells enter the

Options

A. `G_(2)` phase
B. M phase
C. `G_(0)` phase
D. S phase

Answer

**Step-by-Step Text Solution:**

1. **Understanding Cell Cycle Phases**: The cell cycle consists of several phases, including G1, S, G2, and M phases. Each of these phases has specific functions related to cell growth and division.

2. **Identifying Non-Dividing Cells**: Non-dividing cells are those that are not actively preparing to divide. In the context of the cell cycle, these cells can enter a specific phase where they remain inactive.

3. **Recognizing the G0 Phase**: The G0 phase, also known as the quiescent phase, is where non-dividing cells can enter. In this phase, cells are metabolically active but do not proliferate. They may remain in this phase for an extended period until they receive signals to re-enter the cell cycle.

4. **Distinguishing Between Other Phases**:
- The G1 phase is a preparatory phase for cell division.
- The S phase is where DNA replication occurs.
- The G2 phase is where the cell prepares for mitosis.
- The M phase is the actual division phase.

5. **Conclusion**: Therefore, non-dividing cells enter the G0 phase, where they remain inactive until conditions are favorable for division.

**Final Answer**: Non-dividing cells enter the G0 phase.
