**Question:**DNA replication begins at the start of mitosis and meiosis.- [ ] True- [ ] False**Explanation:**This question evaluates the understanding of the timing of DNA replication in the cell cycle. In both mitosis and meiosis, DNA replication occurs during the S phase of interphase, before the actual cell division processes begin. Therefore, the correct answer is "False" because DNA replication does not begin at the start of mitosis or meiosis. **Topic: The Role of Crossing Over in Meiosis****Question: Crossing over during meiosis ensures what?**- ○ cells that divide- ○ genetic variation- ○ genetic continuity- ○ identical cells**Explanation:**Crossing over is a crucial process during meiosis where homologous chromosomes exchange genetic material. This results in genetic variation, which is essential for evolution and the adaptation of species. Understanding how this process contributes to genetic diversity can be vital for studying inheritance patterns, genetic disorders, and the development of new traits in populations.
