Polymerase chain reaction, or PCR, is a laboratory technique used to make multiple copies of a segment of DNA. PCR is very precise and can be used to amplify, or copy, a specific DNA target from a ...

real-time reverse transcription–polymerase chain reaction, or real-time RT–PCR. Fast and accurate, real-time RT–PCR has been critical in detecting, tracking and studying COVID-19. But what is it, and ...

How does it work? How is it different from PCR ... RT–PCR is a variation of PCR, or polymerase chain reaction. The two techniques use the same process except that RT–PCR has an added step of reverse ...

In the polymerase ... resulting chain reaction leads to the formation of a nicked double helix that grows until the hairpin supply is exhausted. Detection of the resulting products does not ...

When the first thermal cyclers for the polymerase chain reaction came out in the 1980s ... of the original DNA accumulate exponentially. Like any thermal cycler, [Urs Gaudenz]’s PocketPCR ...
