Chromosomes are best observed at metphase. For studying the shape, best stage is

Options

A. early prophase
B. anaphase
C. telophase
D. late prophase

Answer

To determine the best stage for studying the shape of chromosomes, we can follow these steps:

### Step-by-Step Solution:

1. **Understanding Chromosome Observation**:
- Chromosomes are best observed during the metaphase stage of cell division. This is when they are most condensed and aligned at the cell's equatorial plane.

2. **Identifying Chromosome Shapes**:
- Chromosomes can be classified based on the position of the centromere:
- **Metacentric**: Centromere is in the center.
- **Submetacentric**: Centromere is slightly off-center.
- **Acrocentric**: Centromere is near one end.
- **Telocentric**: Centromere is at the very end.

3. **Best Stage for Shape Study**:
- While metaphase is ideal for observing chromosomes, the best stage for studying their shape is actually the **anaphase**.
- During anaphase, chromosomes are moving toward opposite poles, and their shapes (V, L, J, I) can be clearly seen as they are separated from their chromatids.

4. **Conclusion**:
- Therefore, the best stage to study the shape of chromosomes is the **anaphase stage** of mitosis.

### Final Answer:
The best stage for studying the shape of chromosomes is the **anaphase stage**.
