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.
Confidence votes 174. DNA has to replicate before mitosis to keep the number of chromosomes and DNA in the cell consistent. Mitosis is the process of reproducing cells by splitting one cell in half to make two. If the DNA didn't replicate, the two daughter cells wouldn't be able to have a complete strand.DNA replicates by dividing in half, then creating a mirror image of itself. Replication gives both strands of DNA an EXACT copy.itosis is the process of reproducing cells by splitting one cell in half to make two.
