what is the full form of PCR?
Ahh, pardon me if I am unable to provide you complete answer. Had read about PCR a long while ago. Its 'Polymerase chain reaction' (PCR) which 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.
Movie 'surrogates' reminds me of PCR ! Hope this helps you ;)
