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.
It is highly important for DNA to be able to replicate itself so that chromosomes can be copied to give the exact same genetic code to every new cell that is made. It is the base pairing rules that allow DNA to replicate. <br /><br /> DNA replication takes part before cell division during mitosis and meiosis.
