In anaphase, a metacentric chromosome appears :-

Options

A. I shaped
B. J-shaped
C. V-shaped
D. L-shaped

Answer

To solve the question regarding the appearance of a metacentric chromosome during anaphase, we can follow these steps:

### Step-by-Step Solution:

1. **Understand Chromosome Types**:
- Chromosomes can be classified based on the position of their centromere. The main types are:
- **Metacentric**: Centromere is located in the middle, resulting in two equal arms.
- **Submetacentric**: Centromere is slightly off-center, resulting in one arm being longer than the other.
- **Acrocentric**: Centromere is located closer to one end, resulting in one very short arm and one long arm.
- **Telocentric**: Centromere is at one end of the chromosome.

2. **Identify the Stage of Cell Division**:
- Anaphase is the stage in cell division where sister chromatids are pulled apart towards opposite poles of the cell.

3. **Determine the Shape of Metacentric Chromosomes in Anaphase**:
- During anaphase, metacentric chromosomes will appear in a characteristic shape due to the equal length of their arms. As the chromatids separate, they take on a V-shape appearance.

4. **Evaluate the Options**:
- **I-shape**: Incorrect, as this shape corresponds to telocentric chromosomes.
- **J-shape**: Incorrect, as this shape corresponds to acrocentric chromosomes.
- **V-shape**: Correct, as this is the shape of metacentric chromosomes during anaphase.
- **L-shape**: Incorrect, as this shape corresponds to submetacentric chromosomes.

5. **Conclusion**:
- The correct answer is that a metacentric chromosome appears in a **V shape** during anaphase.

### Final Answer:
The metacentric chromosome appears in a **V shape** during anaphase.
