Add reagents in following order: water, buffer, dNTPs, Mg CL2, template primers, Taq polymerase. A typical PCR procedure begins by heat-denaturation of a DNA sample into single strands. Primer is needed because DNA polymerase can add a nucleotide only onto a preexisting 3′-OH group to add the first nucleotide. The Polymerase chain reaction (PCR), first envisaged in 1984 by Kary Mullis, has revolutionized life sciences and has become an essential technique in many aspects of science, including clinical diagnostics, forensics and genetic engineering. 0 COLD-PCR (co-amplification at lower denaturation temperature-PCR) is a modified PCR protocol that enriches variant alleles from a mixture of wildtype and mutation-containing DNA. PCR is shorthand for a simple but very useful procedure in molecular biology called the p olymerase c hain r eaction. Be sure to use a sequence-specific primer. Quantitative PCR. It may be necessary to determine the optimal conditions for each individual component. PCR methods are therefore particularly valuable when amounts of RNA are low, since the fact that PCR involves an amplification step means that it is more sensitive.
