In mitotic metaphase the limbs of the chromosomes occur

Options

A. On the equator
B. In different directions
C. In divaricate condition
D. All the above

Answer

**Step-by-Step Solution:**

1. **Understanding Metaphase**: In mitotic metaphase, chromosomes are aligned at the metaphase plate, which is the equatorial plane of the cell. This is where the centromeres of the chromosomes are positioned.

2. **Identifying the Limbs of Chromosomes**: Each chromosome consists of two arms or limbs, which are the sections of the chromosome that extend from the centromere.

3. **Positioning of Limbs**: During metaphase, the limbs of the chromosomes are oriented in opposite directions. For example, one limb may extend upwards while the other limb extends downwards.

4. **Analyzing the Options**:
- **Option 1 (On the equator)**: This is incorrect because the limbs are not at the equator; the centromeres are.
- **Option 2 (In different directions)**: This is correct as the limbs extend in opposite directions.
- **Option 3 (In divaricate condition)**: This refers to a stretched condition seen in anaphase, not metaphase, so it is incorrect.
- **Option 4 (All of the above)**: Since not all options are correct, this option is also incorrect.

5. **Conclusion**: The correct answer is **Option 2: In different directions**.
