That work did not lead them to a new technique, but an ancient ... DNA from the suspected pathogen during cycles of heating and cooling. To run such diagnostics reliably, practitioners need a PCR ...

PCR-machines are used for replication of DNA, detecting DNA sequences, carrying out DNA fingerprinting, forensic analysis, and molecular cloning, diagnosing genetic diseases, and detecting ...

while the others are used for building the DNA and adding marker labels to the strands, which are then used to detect the virus. The mixture is then placed in an RT–PCR machine. The machine cycles ...
