Polymerase Chain Reaction (PCR) is the Technique in molecular genetics permitting the analysis of any short sequence of DNA or RNA.
A given DNA segment can be quickly multiplied (amplified) into millions or billions of copies using the polymerase chain reaction (abbreviated PCR), allowing for more in-depth analysis. In PCR, a section of the genome to be amplified is chosen using shorter synthesized Fragments of DNA called primers. Multiple sets of DNA polymerase are then utilized to amplify that segment. A method used during molecular genetics to make multiple copies of a specific DNA region is called a polymerase chain reaction, or PCR. A scientist from the United States named Kary Mullis created this method in 1983. A tiny DNA segment may now be copied millions of times thanks to PCR.
