random amplified polymorphic DNA
random amplified polymorphic DNA (RAPD) A technique in molecular biology for the rapid assignation of DNA-based
character states for
phylogenetic analysis. The technique uses the
polymerase chain reaction to amplify any genomic region containing an arbitrary sequence. The resulting amplified DNA fragment sizes are then used as characters for phylogenetic analysis.
