Detailed explanation-1: -Polymerase chain reaction (abbreviated PCR) is a laboratory technique for rapidly producing (amplifying) millions to billions of copies of a specific segment of DNA, which can then be studied in greater detail.

Detailed explanation-2: -Polymerase chain reaction, or PCR, is a technique to make many copies of a specific DNA region in vitro (in a test tube rather than an organism). PCR relies on a thermostable DNA polymerase, Taq polymerase, and requires DNA primers designed specifically for the DNA region of interest.

Detailed explanation-3: -PCR (Polymerase Chain Reaction) is a technique that is used to make millions of copies of a sample DNA very rapidly. After the completion of each cycle, two copies of DNA samples are produced.
