Replication of DNA in meiosis occur during :-

Options

A. S - phase
B. S - phase and lepto
C. S - phase and zygo
D. All of these

Answer

To determine when DNA replication occurs during meiosis, let's break down the steps involved:

### Step-by-Step Solution:

1. **Understanding Meiosis**: Meiosis consists of two main divisions: Meiosis I and Meiosis II. Each division has several phases: prophase, metaphase, anaphase, and telophase.

2. **Phases of Meiosis**: In Meiosis I, the phases are:
- Prophase I (which includes sub-stages: leptotene, zygotene, pachytene, diplotene, and diakinesis)
- Metaphase I
- Anaphase I
- Telophase I
- Prophase II
- Metaphase II
- Anaphase II
- Telophase II

3. **DNA Replication**: DNA replication occurs during the S phase of the cell cycle, which is part of interphase. Interphase occurs before meiosis begins.

4. **Identifying the Correct Phase**: The question asks specifically about meiosis. The replication of DNA occurs during the S phase of interphase, before the actual meiotic divisions start.

5. **Conclusion**: Therefore, the correct answer is that DNA replication in meiosis occurs during the S phase of interphase.

### Final Answer:
Replication of DNA in meiosis occurs during the **S phase** of interphase.
