Polymerase chain reaction (PCR) (article) | Khan Academy The steps of PCR The key ingredients of a PCR reaction are Taq polymerase, primers, template DNA, and nucleotides (DNA building blocks). The ingredients are assembled in a tube, along with cofactors needed by the enzyme, and are put through repeated cycles of heating and cooling that allow DNA to be synthesized. The basic steps are: Standard PCR Protocol - Sigma-Aldrich How to do PCR. A standard polymerase chain reaction (PCR) setup consists of four steps: Add required reagents or mastermix and template to PCR tubes.

polymerase chain reaction | Definition & Steps | Britannica PCR is a three-step process that is carried out in repeated cycles. The initial step is the denaturation, or separation, of the two strands of the DNA molecule. This is accomplished by heating the starting material to temperatures of about 95 °C (203 °F). Each strand is a template on which a new strand is built. Polymerase Chain Reaction (PCR): Steps in This DNA Test PCR (polymerase chain reaction) is a method to analyze a short sequence of DNA (or RNA) even in samples containing only minute quantities of DNA or RNA. PCR is used to reproduce (amplify) selected sections of DNA or RNA. Previously, amplification of DNA involved cloning the segments of interest into vectors for expression in bacteria, and took ...
