DNA Fingerprinting

More information in Books or onNLM PubMed
Definition: A technique for identifying individuals of a species that is based on the uniqueness of their DNA sequence. Uniqueness is determined by identifying which combination of allelic variations occur in the individual at a statistically relevant number of different loci. In forensic studies, RESTRICTION FRAGMENT LENGTH POLYMORPHISM of multiple, highly polymorphic VNTR LOCI or MICROSATELLITE REPEAT loci are analyzed. The number of loci used for the profile depends on the ALLELE FREQUENCY in the population.  DNA FOOTPRINTING is available; do not confuse X ref DNA PROFILING with GENE EXPRESSION PROFILING
