Now, during interface, we have a phase known as the S phase. And during the S phase of interface, we have the DNA that is replicated. And in humans, where we have 46 chromosomes, all 46 chromosomes, or 23 pairs of homologous chromosomes, are basically replicated during the process of S phase in interface. So our DNA is actually replicated before meiosis actually takes place in the same way that the DNA is replicated before mitosis takes place. Now, what exactly do we mean by this replication process? Let's take a look at the following diagram.
