V-shaped anaphasic chromosome is

Options

A. Metacentric
B. Sub-metacentric
C. Acrocentric
D. Telocentric

Answer

### Step-by-Step Solution:

1. **Understanding Chromosomes**:
- Chromosomes are structures within cells that contain DNA. They are made up of two sister chromatids joined at a region called the centromere.

2. **Identifying Chromosome Types**:
- Chromosomes can be classified based on the position of the centromere. The main types are:
- **Metacentric**: Centromere is in the middle, resulting in two equal arms.
- **Sub-metacentric**: Centromere is slightly off-center, resulting in one arm being longer than the other.
- **Acrocentric**: Centromere is near one end, resulting in one very short arm and one long arm.
- **Telocentric**: Centromere is at one end, resulting in a single arm.

3. **V-shaped Anaphasic Chromosomes**:
- During the anaphase stage of cell division, chromosomes are pulled apart.
- Metacentric chromosomes, which are X-shaped before separation, become V-shaped as the sister chromatids are pulled towards opposite poles of the cell.

4. **Conclusion**:
- The V-shaped anaphasic chromosome is specifically associated with metacentric chromosomes due to their equal arms and the way they separate during cell division.

5. **Final Answer**:
- The V-shaped anaphasic chromosome is **metacentric**.
