Denaturation : This step involves heating the reaction mixture to 94°C for 15-30 seconds. Splet03. apr. 2024 · The second step uses the cDNA as a template to quantify the mRNA. In the second reaction, along with all PCR reagents, the Taq DNA polymerase completes the reaction and quantification using a dye or probe. Here we do not need a reverse transcriptase. The second reaction quantifies our cDNA (formed from the first step).

SpletPCR or Polymerase Chain Reaction is a technique used in molecular biology to create several copies of a certain DNA segment. This technique was developed in 1983 by Kary Mullis, an American biochemist. PCR has made it possible to generate millions of copies of a small segment of DNA. ...
