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.
Best Answer: 1. PCR is used to amplify DNA: that is, to (exponentially) increase the number of molecules of a particular DNA region. And because PCR uses primers, it can isolate a particular DNA sequence of interest from among an enormous, complex mix of millions of various DNA sequences: you can proverbially find the DNA needle in a haystack. 2. PCR is important because it allows scientists to work with DNAs and DNA samples that they previously could not.
