One example is the polymerase chain reaction (PCR), a standard technique which employs enzymes to churn out millions of copies of a DNA sequence and involves cycles of gentle heating and cooling.

The polymerase chain reaction (PCR) is a scientific technique in molecular biology to amplify a single or a few copies of a piece of DNA across several orders of magnitude, generating thousands to millions of copies of a particular DNA sequence.

FORBES: There is No Great Stagnation

For years, he had been making the case that polymerase chain reaction (PCR) would be the best way to test for the existence of Earth-like DNA on Mars.
