Which of the following is wrong about `G_(1)` phase?

Options

A. G-1 Stage followed by Mitosis
B. Cell is metabolically active
C. Cell grows continuously
D. Cell does not replicate its DNA

Answer

To determine which statement about the G1 phase is incorrect, we need to analyze the characteristics of the G1 phase in the cell cycle. Here’s a step-by-step breakdown:

### Step-by-Step Solution:

1. **Understanding the Cell Cycle**:
- The cell cycle consists of two main stages: the mitotic stage (M phase) and interphase. Interphase is further divided into G1, S, and G2 phases.

2. **Identifying the G1 Phase**:
- The G1 phase occurs immediately after the mitotic phase. It is a period of growth and preparation for DNA synthesis.

3. **Functions of the G1 Phase**:
- During G1, the cell is metabolically active, meaning it is engaged in various biochemical processes.
- The cell grows in size and synthesizes proteins and organelles necessary for DNA replication and cell division.

4. **DNA Replication**:
- It is important to note that DNA replication does not occur during the G1 phase. Instead, it takes place during the S phase (Synthesis phase) that follows G1.

5. **Evaluating the Statements**:
- **Statement 1**: "G1 stage is followed by mitosis." - This is incorrect. G1 is followed by the S phase, not mitosis.
- **Statement 2**: "Cell is metabolically active." - This is correct.
- **Statement 3**: "Cell grows continuously." - This is correct.
- **Statement 4**: "Cell does not replicate its DNA." - This is also correct.

6. **Conclusion**:
- The incorrect statement about the G1 phase is that it is followed by mitosis. Instead, it is followed by the S phase.

### Final Answer:
The wrong statement about the G1 phase is: "G1 stage is followed by mitosis."
