Select the correct statement about G 1 phase

Options

A. (a) Cell is metabolically inactive
B. (b) DNA in the cell does not replicate
C. (c) It is not a phase of synthesis of macro- molecuIes
D. (d) Cell stops growing

Answer

To solve the question regarding the correct statement about the G1 phase of the cell cycle, we will analyze each option provided and determine which one is accurate.

### Step-by-Step Solution:

1. **Understanding the G1 Phase**:
- The G1 phase, also known as the first gap phase or growth phase, is a part of interphase in the cell cycle. It occurs before the S phase (where DNA replication takes place).

2. **Analyzing the Options**:
- **Option A**: "A cell is metabolically inactive."
- This statement is incorrect. During the G1 phase, the cell is metabolically active, engaging in various biochemical processes.

- **Option B**: "DNA in the cell does not replicate."
- This statement is correct. DNA replication occurs in the S phase, not in the G1 phase. Therefore, this option is a potential correct answer.

- **Option C**: "It is not the phase of synthesis of macromolecules."
- This statement is incorrect. The G1 phase is indeed a phase of macromolecule synthesis, including proteins and nucleotides, which are essential for the upcoming S phase.

- **Option D**: "Cell stops growing."
- This statement is also incorrect. The G1 phase is characterized by cell growth and preparation for DNA synthesis, meaning the cell does not stop growing during this phase.

3. **Conclusion**:
- After analyzing all the options, the only correct statement about the G1 phase is **Option B**: "DNA in the cell does not replicate."

### Final Answer:
The correct statement about the G1 phase is **Option B**: "DNA in the cell does not replicate."
