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.
What are the reasons that replication occurs. for growth, repairing injuries, reproduction, maintenance, when cells get too large, and to fight illness. What are the steps of replication>. -DNA helix unwinds and unzips (breaks the hydrogen bonds) and the enzyme helicase does this. -DNA nulceotides join (base pair) with DNA bases on both parent strands using the enqyme DNA polymerase. -The strands rewind and rezip so they can be used over again.
