Cooling is necessary for rehybridization and for attachment of the primers to the original or newly synthesized DNA strands, but near-boiling temperatures will still not denature a certain enzyme of Thermus aquaticus, commonly known as Taq [TACK]. FTP, name this technique developed for large scale amplification of DNA, first proposed by Kary Mullis in 1983.
