The cells which enter _______ phase start differentiating into specific types of cell.

Options

A. `G_(1)`
B. `G_(2)`
C. S
D. `G_(0)`

Answer

**Step-by-Step Solution:**

1. **Understanding the Cell Cycle**: The cell cycle consists of several phases, including G1, S, G2, and M phases. The G0 phase is a resting state where cells can exit the cycle.

2. **Identifying the Differentiation Phase**: Among these phases, the G0 phase is specifically known for differentiation. Cells that enter this phase do not actively divide but instead begin to specialize into specific types of cells.

3. **Role of G0 Phase**: In the G0 phase, cells can differentiate into various specialized cells. For example, a zygote can develop into different cell types as it progresses through development.

4. **Conclusion**: Therefore, the correct answer to the question is that the cells which enter the **G0 phase** start differentiating into specific types of cells.

**Final Answer**: The cells which enter **G0 phase** start differentiating into specific types of cell.
