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 ...

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 ...

The PCR machine increases and decreases the temperature of the sample in automatic, programmed steps. Initially, the mixture is heated to denature, or separate, the double-stranded DNA template ...

“Ancient DNA is like a time machine. It takes you back in time to the people whose bones you are discovering from cultures of ...

The mixture is then placed in an RT–PCR machine. The machine cycles through temperatures that heat and cool the mixture to trigger specific chemical reactions that create new, identical copies of the ...
