Edited by the inventor of PCR and two prominent experts in PCR techniques, this first comprehensive handbook on the Polymerase Chain Reaction has the most up to date methodological protocols from the world's leading laboratories. Included are exciting new techniques and enhanced methods, previously unavailable in book form, that show the novice and experienced PCR user exactly how they can optimize their results. The applications chapters are quite unique, with the foremost researchers providing not only protocols, but explaining why PCR has revolutionized their particular field. Future enhancements of PCR as well as new potential uses are discussed. Readers will learn how PCR has changed the face of diagnostic testing, cancer research, genetics, forensics, plant biology, DNA sequencing, gene therapy, and much more! Nearly forty chapters have been extensively reviewed and checked for accuracy and breadth of subject matter.

James D. Watson When, in late March of 1953, Francis Crick and I came to write the first Nature paper describing the double helical structure of the DNA molecule, Francis had wanted to include a lengthy discussion of the genetic implications of a molecule whose struc ture we had divined from a minimum of experimental data and on theoretical argu ments based on physical principles. But I felt that this might be tempting fate, given that we had not yet seen the detailed evidence from King's College. Nevertheless, we reached a compromise and decided to include a sentence that pointed to the biological significance of the molecule's key feature-the complementary pairing of the bases. "It has not escaped our notice," Francis wrote, "that the specific pairing that we have postulated immediately suggests a possible copying mechanism for the genetic material." By May, when we were writing the second Nature paper, I was more confident that the proposed structure was at the very least substantially correct, so that this second paper contains a discussion of molecular self-duplication using templates or molds. We pointed out that, as a consequence of base pairing, a DNA molecule has two chains that are complementary to each other. Each chain could then act ". . . as a template for the formation on itself of a new companion chain, so that eventually we shall have two pairs of chains, where we only had one before" and, moreover, " ...
