Polymorphic, random amplification analysis

Plant DNA analysis has been increasing over the past couple of years because of its ability to pinpoint the origin of drug-related plant material [ 101,102]. Plant STRs are not yet well characterized however, other molecular methods can be combined with capillary gel electrophoresis to establish the identity of plant species [103]. These techniques include amplified fragment length polymorphism (AFLP), random amplification of polymorphic DNA (RAPD), and other similar random primer annealing techniques used for mutation detection. 

Random amplified polymorphic DNA analysis is one method used for the same purpose but based on the utilization of short arbitrary (about 10 bases) primers yielding a number of electrophoretic species-specific amplification products for given reaction conditions. The method was applied in species determination in foods, especially in meat products [52].
