The polymerase chain reaction (PCR) can amplify a region of DNA from any source, even from a single cell’s worth of DNA or from fragments of DNA obtained from a fossil. This amplification usually takes just a few hours, generating millions of copies of the desired target DNA sequence. SpletIn this study the influence of amplicon length on PCR yield in real-time PCR was analyzed, to show that the advantage of using small targets for GMO detection is linked to an intrinsic real-time PCR property. 2.
