In meiosis, the chromosomes replicate during :

Options

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

Answer

**Step-by-Step Solution:**

1. **Understanding Meiosis**: Meiosis is a type of cell division that reduces the chromosome number by half, resulting in four haploid cells from one diploid parent cell. It consists of two main stages: Meiosis I and Meiosis II.

2. **Identifying Phases of Meiosis**: The phases of meiosis include Prophase, Metaphase, Anaphase, and Telophase for both Meiosis I and Meiosis II. However, before meiosis begins, the cell goes through Interphase.

3. **Role of Interphase**: Interphase is divided into three sub-phases: G1 phase, S phase, and G2 phase. During Interphase, the cell prepares for division.

4. **Chromosome Replication**: The key phase where chromosome replication occurs is the S phase (Synthesis phase) of Interphase. During this phase, DNA is replicated, resulting in two identical copies of each chromosome.

5. **Conclusion**: Therefore, in meiosis, chromosomes replicate during the S phase of Interphase.

**Final Answer**: In meiosis, the chromosomes replicate during the S phase of Interphase.
