The template is the DNA that contains the target you want to amplify. The primers are synthetic DNA molecules whose sequence matches a region flanking the target you are trying to amplify. It is possible nowadays, to chemically synthesize DNA molecules of any given base sequence, to use as primers.CR stands for Polymerase Chain Reaction, a method for amplifying DNA in vitro. Where, in cloning DNA into a plasmid, the DNA is amplified by the bacterial cell when it replicates the plasmid, PCR amplifies DNA in a test-tube.
