Terminalisation occurs during

Options

A. Mitosis
B. Diakinesis
C. Meiosis II
D. Cytokinesis

Answer

**Step-by-Step Solution:**

1. **Understanding Terminalization**: Terminalization refers to the process of the chiasmata being removed or disappearing from the chromosomes. Chiasmata are the points where homologous chromosomes are attached after crossing over during meiosis.

2. **Identifying Chiasmata**: Chiasmata form during the process of crossing over, which occurs in meiosis. They represent the physical exchange of genetic material between homologous chromosomes.

3. **Mechanism of Terminalization**: The terminalization of chiasmata occurs due to the tight condensation of chromosomes. As the chromosomes condense, the chiasmata can slip off or slide from the tips of the chromosomes.

4. **Timing of Terminalization**: Terminalization occurs during meiosis, specifically in prophase I. Prophase I is divided into five stages, and terminalization specifically occurs in the last stage of prophase I, which is called diakinesis.

5. **Conclusion**: Therefore, terminalization occurs during diakinesis, which is a stage of meiosis.

**Final Answer**: Terminalization occurs during diakinesis in meiosis.
