Chromosomes separation and centromere division occur in

Options

A. Anaphase
B. Anaphase I
C. Anaphase II
D. More than one option is correct

Answer

**Step-by-Step Solution:**

1. **Understanding Chromosome Structure**:
- Chromosomes consist of two sister chromatids that are joined together at a region called the centromere.

2. **Role of Centromere**:
- The centromere serves as the attachment point for spindle fibers during cell division. It is crucial for the movement of chromatids to opposite poles of the cell.

3. **Phases of Cell Division**:
- There are different phases of cell division: prophase, metaphase, anaphase, and telophase. In meiosis, there are also anaphase 1 and anaphase 2.

4. **Anaphase 1**:
- In anaphase 1 of meiosis, homologous chromosomes are separated, but the centromeres do not divide. The sister chromatids remain attached at the centromere.

5. **Anaphase 2**:
- In anaphase 2, which occurs in meiosis, the sister chromatids are separated, and the centromeres divide. This is the stage where chromosome separation and centromere division occur.

6. **Conclusion**:
- Therefore, the correct answer to the question is that chromosome separation and centromere division occur in **anaphase 2**.
