V, J and L shaped chromosome occurs in :–

Options

A. Prophase
B. Anaphase
C. Metaphase
D. Telophase

Answer

To determine where V, J, and L-shaped chromosomes occur, we need to analyze the different phases of cell division, particularly during mitosis.

### Step-by-Step Solution:

1. **Understanding Chromosome Shapes**:
- Chromosomes can take various shapes based on their structure and the phase of cell division. The V-shaped chromosomes are typically metacentric, J-shaped chromosomes are acrocentric, and L-shaped chromosomes can also be metacentric.

2. **Identifying the Phases of Mitosis**:
- Mitosis consists of several phases: Prophase, Metaphase, Anaphase, and Telophase. Each phase has distinct characteristics regarding chromosome behavior and appearance.

3. **Analyzing Prophase**:
- During prophase, chromosomes condense and become visible, but they do not exhibit the distinct V, J, or L shapes. Instead, they appear as thick, rod-like structures. Therefore, this phase does not show the required chromosome shapes.

4. **Analyzing Metaphase**:
- In metaphase, chromosomes align at the metaphase plate, and while they are distinct, the shapes of V, J, and L are not specifically noted. Most chromosomes appear as X-shaped due to the sister chromatids being joined at the centromere.

5. **Analyzing Anaphase**:
- Anaphase is characterized by the separation of sister chromatids, which move towards opposite poles of the cell. During this phase, the chromosomes can adopt V, J, and L shapes as they are pulled apart. This is the phase where these shapes are most commonly observed.

6. **Analyzing Telophase**:
- In telophase, the chromosomes begin to de-condense, and the nuclear membrane reappears. The distinct shapes of V, J, and L are not visible in this phase as the chromosomes are transitioning back to chromatin.

7. **Conclusion**:
- Based on the analysis, the correct answer is that V, J, and L-shaped chromosomes occur during **Anaphase**.

### Final Answer:
The V, J, and L-shaped chromosomes occur in **Anaphase**.
