Polymerase chain reaction, or PCR, is a laboratory technique ... the temperature of the sample in automatic, programmed steps. Initially, the mixture is heated to denature, or separate, the ...

PCR amplifies DNA in a three-step process: denaturation ... The coils rapidly heat a reaction block up to the 99°C denaturation temperature, the fan brings that down to the 68°C needed for ...

The polymerase chain reaction — or PCR — test is the gold ... which utilizes a unique two-step priming process for target binding. This greatly minimizes the amplification of off-target ...
