The antiparallel structure of DNA is important in DNA replication because it replicates the leading strand one way and the lagging strand the other way. During DNA replication the leading strand is replicated continuously whereas the lagging strand is replicated in segments known as Okazaki fragments.
DNA replicatioin occurs before mitosis. It happens during INTERPHASE. DNA has to replicate because DNA contains the genetic blueprint for the cell. It tells the cell how to function and how it is to form. Also, the daughter cells must each have their own set of equal DNA. Shortly before cell division (Mitosis).
