Shape of metacentric chromosome in anaphase is

Options

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

Answer

To determine the shape of a metacentric chromosome during anaphase, we can follow these steps:

### Step-by-Step Solution:

1. **Understand Metacentric Chromosomes**:
- Metacentric chromosomes have their centromere located in the center, resulting in two equal-length arms.

2. **Identify Chromosome Shape During Anaphase**:
- During anaphase, the chromosomes are pulled apart as the spindle fibers contract, separating the sister chromatids and moving them toward opposite poles of the cell.

3. **Visualize the Chromosome Movement**:
- As the sister chromatids are pulled apart, they begin to take on a specific shape due to the tension and movement.

4. **Determine the Shape**:
- The shape of the metacentric chromosome during anaphase is typically described as V-shaped. This is because as the chromatids separate, they form a V-like structure.

5. **Conclusion**:
- Therefore, the correct answer is that the shape of a metacentric chromosome during anaphase is V-shaped.

### Final Answer:
The shape of a metacentric chromosome in anaphase is V-shaped.
