What is PCR
Polymerase Chain Reaction or PCR is a common tool used in the field of biology to amplify DNA or RNA. Invented by Dr. Kary Mullis, PCR is conducted trough cycling DNA, primers and enzyme through various temperatures. Generally starting with a value near and above 90 degrees Celsius; used to break the Hydrogen bonds between double strands a process called denaturation. The machine then cools down to annealing temperature, with values near 50-60 degrees, at this point primers are able to attach to the template strand of DNA. This stage is then followed by extension temperature, around 72 degrees, at this point the polymerase is able to extend and add nucleotides to the primer.
