Web20 sep. 2024 · The process of the PCR is subdivided into three stages: denaturation, annealing and elongation. RT–PCR is a variation of PCR which use the same process except that RT–PCR has an added step of reverse transcription of RNA to DNA at first to allow for amplification. The first cycle is reverse transcription to synthesize cDNA. Web18 jan. 2024 · Polymerase chain reaction (PCR) is a common laboratory technique used in research and clinical practices to amplify, or copy, small segments of genetic material. PCR is sometimes called “molecular photocopying,” and it is incredibly accurate and sensitive. Short sequences called primers are used to selectively amplify a specific DNA sequence.
