1. Introduction

The polymerase chain reaction (PCR) is an incredibly versatile technique that has made a profound impact on many areas of biology. PCR is based on the use of oligonucleotides, which flank the region of DNA of interest and which are complementary to sequences on either DNA strand, to prime the replication of each strand by Taq DNA polymerase. This enzyme is thermostable, and consequently, one can go through cycles of template denaturation and renaturation after each round of replication and exponentionally amplify the sequence of interest. This procedure is very sensitive, and as such, it allows one to amplify, isolate, and utilize specific DNA sequences from vanishingly small quantities of starting material using either genomic or cDNA as a substrate.

PCR can also be used to facilitate the isolation of genes that are evolution-arily related, such as cognate genes from different species or multiple members of given gene families. In these cases, one is often trying to...
