In which phase of Interphase, the cell is metabolically active and grows continuously

Options

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

Answer

To answer the question "In which phase of Interphase, the cell is metabolically active and grows continuously?", we will analyze the different phases of Interphase: G1, S, and G2.

### Step-by-Step Solution:

1. **Understanding Interphase**: Interphase is the phase of the cell cycle where the cell prepares for division. It consists of three main phases: G1 (Gap 1), S (Synthesis), and G2 (Gap 2).

2. **Analyzing the G1 Phase**:
- The G1 phase is the first phase of Interphase.
- During this phase, the cell is metabolically active, meaning it is engaged in various biochemical processes.
- The cell also grows continuously during this phase, synthesizing proteins and RNA necessary for DNA replication and cell division.

3. **Analyzing the S Phase**:
- The S phase is where DNA replication occurs.
- While the cell is active, its primary focus is on duplicating its genetic material rather than general growth.

4. **Analyzing the G2 Phase**:
- The G2 phase follows the S phase.
- In this phase, the cell continues to grow and prepares for mitosis by synthesizing proteins and organelles.
- However, the main focus is on preparing for cell division rather than continuous growth.

5. **Conclusion**:
- Among the three phases, the G1 phase is the one where the cell is most actively growing and metabolically active.
- Therefore, the correct answer to the question is **G1 phase**.

### Final Answer:
The cell is metabolically active and grows continuously in the **G1 phase** of Interphase.
