Analyze the statements and select the correct option.
a) The cell cycle gets completed in G1-S-G2-M phase.
b) G1 phase corresponds to the interval between mitosis and initiation of DNA replication.
c) In the G1 phase, the cell is metabolically active and DNA replicates.

Options

A. a and b are correct .
B. only c is incorrect
C. only b is correct
D. a and c are incorrect

Answer

To analyze the statements regarding the cell cycle and select the correct option, we need to evaluate each statement one by one.

### Step-by-Step Solution:

1. **Understanding the Cell Cycle**:
- The cell cycle consists of four main phases: G1 (Gap 1), S (Synthesis), G2 (Gap 2), and M (Mitosis).
- The cell cycle is typically represented as G1 → S → G2 → M.

2. **Evaluating Statement A**:
- **Statement A**: "The cell cycle gets completed in G1-S-G2-M phase."
- This statement is correct because the cell cycle indeed progresses through these phases in the given order.

3. **Evaluating Statement B**:
- **Statement B**: "G1 phase corresponds to the interval between mitosis and initiation of DNA replication."
- This statement is also correct. The G1 phase occurs after mitosis (M phase) and before the S phase, where DNA replication begins.

4. **Evaluating Statement C**:
- **Statement C**: "In the G1 phase, the cell is metabolically active and DNA replicates."
- This statement is incorrect. While it is true that the cell is metabolically active during the G1 phase, DNA replication does not occur in G1; it occurs in the S phase.

5. **Conclusion**:
- Based on the evaluations:
- Statement A is correct.
- Statement B is correct.
- Statement C is incorrect.
- Therefore, the correct options are A and B.

### Final Answer:
The correct options are A and B.
