Noun1.DNA fingerprint - biometric identification obtained by examining a person's unique sequence of DNA base pairs; often used for evidence in criminal law cases
biometric authentication, biometric identification, identity verification - the automatic identification of living individuals by using their physiological and behavioral characteristics; "negative identification can only be accomplished through biometric identification"; "if a pin or password is lost or forgotten it can be changed and reissued but a biometric identification cannot"

Genetic differences in DNA can be useful for detecting a few cancerous cells hidden in normal tissues or distinguishing between different individuals as a DNA fingerprint. The two common types of DNA variants are short tandem repeats (STRs)--a short segment of DNA that occurs multiple times in a series--and single nucleotide polymorphisms (SNPs)--a single DNA base at a location that is different between cells or individuals.
As a DNA fingerprint pattern could only fit one person out of myriads of people, according to Jewish law a specific DNA fingerprint pattern falls under the category of umdenah demukhha (a totally obvious and logical assumption which is so overwhelmingly apparent that we accept it as fact) (COHEN 2000).
Professor Ian Findlay, head of health sciences at Australia's Southbank Institute of Technology, near Brisbane, took swabs from the saliva under the seal and stamp of the envelope, as well as bloodstains, to glean a DNA fingerprint.
"If we want to use PFGE for source tracking in a large watershed like the Santa Ana River, a very extensive DNA fingerprint library is needed, because our study shows that even a minor change in the DNA fingerprint can significantly affect clonal groupings," Ibekwe explains.
Investigators are using pulsed-field gel electrophoresis to determine DNA fingerprint patterns.
Such unambiguous identification is feasible via DNA fingerprint analysis of single cells, as has been shown with candidate target cells preenriched and defined on the basis of biochemical markers (10).
Building on this idea, ask students "What is meant by a DNA fingerprint?" I usually introduce the concept that because everyone has their own unique sequence of DNA molecules, we can use DNA to create a one-of-a-kind pattern just as police officers do when they collect fingerprints.
As of July 31,2009,80 people from 31 states were reportedly infected with a strain of E coli 0157:H7 with a particular DNA fingerprint. Of those cases, 35 people have been hospitalized and 10 have developed hemolytic uremic syndrome.
Isolates were fingerprinted using standard techniques: IS6110 was used as the initial DNA fingerprinting technique,[11] and pTBN12 was used as the secondary DNA fingerprinting technique for isolates that had fewer than 6 hybridizing bands with IS6110.[12] The DNA fingerprint results were interpreted without knowledge of the clinical characteristics of the patients.
Each bacterial substrain has a unique rep-PCR DNA fingerprint, a molecular version of the UPC barcodes used in grocery stores.
