Agarose is used to separate DNA because it has a neutral charge and low chemical complexity - meaning it is unlikely to react with biomolecules. It is also an easily cast and handled matrix. Plus, samples are very easy to recover when you use agarose gel. 4 people found this useful.
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.
