The chromosome morphology is best studied during

Options

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

Answer

To determine when chromosome morphology is best studied, we need to analyze the different phases of cell division, particularly focusing on mitosis. Here’s a step-by-step solution:

### Step-by-Step Solution:

1. **Identify the Phases of Mitosis**: Mitosis consists of several phases: prophase, metaphase, anaphase, and telophase. Each phase has distinct characteristics regarding chromosome structure.

2. **Examine Prophase**:
- During prophase, chromatin condenses to form visible chromosomes. However, at this stage, the chromosomes are not fully matured and are still in the process of forming. Thus, the morphology is not clearly defined.

3. **Examine Metaphase**:
- In metaphase, chromosomes are fully condensed and aligned at the cell's equatorial plane. This arrangement allows for the best visualization of chromosome structure, making it the ideal phase for studying chromosome morphology.

4. **Examine Anaphase**:
- During anaphase, the sister chromatids are pulled apart towards opposite poles of the cell. At this point, the chromosomes are separating, which makes it difficult to study their morphology.

5. **Examine Interphase**:
- Interphase is the stage where the cell is not dividing. Chromosomes are in the form of chromatin and are not visible as distinct structures, making it impossible to study their morphology.

6. **Conclusion**:
- Based on the analysis of these phases, the best phase to study chromosome morphology is during **metaphase**.

### Final Answer:
The chromosome morphology is best studied during **metaphase**.
