Answer:
PCR (polymerase chain reaction)
Explanation:
PCR was developed in 1983 by Kary B. Mullis, an American biochemist who won the Nobel Prize for Chemistry in 1993 for this invention.
Is a technique used to make numerous copies (quickly and accurately) of a specific segment of DNA.
PCR enables investigators to obtain large quantities of DNA that are required for various experiments and procedures in medical diagnostics, molecular biology, forensic analysis, and even evolutionary biology.
As this makes possible to amplified DNA from a wide range of sources, the technique has been applied to many fields.
Example: PCR is used to diagnose genetic disease and to detect low levels of viral infection.
