What is peculiar about `G_(0)`, phase?

Explanation

### Step-by-Step Solution:

1. **Understanding the Cell Cycle**: The cell cycle consists of several phases, including G1, S, G2, and M phases. Each of these phases plays a crucial role in cell division and growth.

2. **Identifying the G0 Phase**: The G0 phase, also known as the "quiescent phase," is a distinct state that some cells enter after the G1 phase. It is important to note that not all cells will proceed to divide after G1; some will enter G0.

3. **Characteristics of G0 Phase**:
- **Arrested Metabolism**: In the G0 phase, the cell's metabolism is essentially "arrested." This means that while the cell is still alive and may perform basic functions, it is not actively preparing to divide.
