DNA fingerprinting

DNA fingerprinting
DNA fingerprinting n a technique used esp. for identification (as for forensic purposes) by extracting and identifying the base-pair pattern of an individual's DNA called also DNA typing, genetic fingerprinting

* * *

a technique for examining nucleic acids or nucleotides by digestion with a restriction enzyme and electrophoretic separation of the resulting fragements; the separated fragments are transferred to a nylon filter and hybridized with radioactive minisatellite probes. Because the number of repeats characterizing each specific minisatellite varies between individuals, the overall pattern obtained is unique to an individual genome; uses of the technique include identification of individuals and of lineage.
