First thing to remember is that interphase is a stage associated with replication of DNA, and growth.
Once meiosis starts, the purpose is to produce a haploid gamete. So there is no further need of replication or growth.
<em> DNA replication needs to occur because existing cells divide to produce new cells.Each cell needs a full instruction manual to operate properly. So the DNA needs to be copied before cell division so that each new cell receives a full set of instructions!</em>
