Question

When does DNA replication take place during meiosis?
  1. Before Prophase I
  2. Before Prophase II
  3. Both (a) and (b)
  4. DNA replication occurs during meiosis


Solution

The correct option is A Before Prophase I
Meiosis is a type of cell division that occurs in the reproductive cells of sexually reproducing organisms. It reduces the chromosome number by half, resulting in the formation of haploid daughter cells. Meiosis involves two sequential cycles of nuclear and cell division called meiosis I and meiosis II but only a single cycle of DNA replication. This single cycle of DNA replication takes place before prophase I of meiosis I, resulting in the formation of identical sister chromatids.
