The correct Answer is:
**Step-by-Step Solution:** 1. **Understanding the Cell Cycle**: The cell cycle consists of two main phases: Interphase and M phase (mitotic phase). Interphase is further divided into three sub-phases: G1 phase, S phase, and G2 phase. 2. **Identifying the S Phase**: The S phase (Synthesis phase) is the specific stage during Interphase where DNA replication occurs. This is crucial because it ensures that each daughter cell receives an identical set of chromosomes. 3. **Interphase Before Meiosis**: Before meiosis begins, the cell must undergo Interphase, which includes the S phase. This means that DNA replication occurs during this Interphase prior to meiosis. 4. **Interkinesis and Cytokinesis**: After meiosis I, there is a phase called interkinesis, which is a short resting phase between meiosis I and meiosis II. During interkinesis, there is no DNA replication. Cytokinesis is the process of cytoplasmic division that occurs after mitosis or meiosis, and it does not involve DNA synthesis. 5. **Conclusion**: Therefore, the stages where DNA replication occurs are during the S phase of Interphase, specifically before meiosis I. The correct answer to the question is that DNA replication occurs during the S phase of Interphase prior to meiosis. **Final Answer**: DNA replication occurs during the S phase of Interphase prior to meiosis. ---
