  5. Rapd ( random amplified polymorphic dna ), which bases on the polymerase chain reaction ( pcr ), is by far one of the most commonly molecular techniques to uncover dna sequence polymorphisms. the basic priciple of this technique is that an arbitrary primer ( usually lobp oligonudetide ) is used to amplify random segments of dna, and a small number of fragments will be amplified when the primer anneals on each strand over a length range. if sequence variation is present at the priming site, then a fragment may not be amplied, so the dna polymorphic can be detected
