Medical term:

fingerprint

[fing´ger-print]

1. an impression of the cutaneous ridges of the fleshy distal portion of a finger.

2. in biochemistry, the characteristic pattern of a peptide after subjection to an analytical technique.

DNA fingerprint (genetic fingerprint) the highly specific hybridization pattern generated by tandem repeats and other patterns of the DNA in an individual's genome.

fin·ger·print

(fing'gĕr-print),

1. An impression of the inked bulb of the distal phalanx of a finger, showing the configuration of the surface ridges, used as a means of identification.
See also: dermatoglyphics, Galton system of classification of fingerprints.

2. Term, sometimes used informally, referring to any analytic method applicable to making fine distinctions between similar compounds or gel patterns, for example, the pattern of an infrared absorption curve or of two-dimensional paper chromatograph.

3. In genetics, the analysis of DNA fragments to determine the identity of a person or the paternity of a child. Synonym(s): genetic fingerprint

fingerprint

(fĭng′gər-prĭnt′)

a. A mark left on a surface by a person's fingertip.

b. An inked impression made of a person's fingertip and used for identification.

2. A distinctive or identifying mark or characteristic: "We can, from his retelling [of the incident], with its particular fingerprint of stresses and omissions, learn a great deal about him" (Mark Slouka).

a. A DNA fingerprint.

b. A chemical fingerprint.

tr.v. finger·printed, finger·printing, finger·prints

To take the fingerprints of.

Chemistry The ‘signature(s)’ that a chemical compound and its metabolites have when analysed by a highly sensitive technique—e.g., HPLC or GC-MS—which may be stored on a computer’s hard disk and electronically matched—‘fingerprinted’—with an unknown specimen for the purpose of identification
Dermatology An inked impression of the fleshy part of the distal phalanx of the finger, which may be classified per the Galton arch-loop-whorl system; increased ulnar loops and decreased whorls and arches have been reported in males with Alzheimer’s disease and Down syndrome
Molecular biology AA pattern of bands on an agarose gel produced by a clone when restricted by a particular enzyme, e.g., HindIII

FINGERPRINT

fingerprint

1. A smudge made when oils from the distal portions of the finger come into contact with an object. Fingerprints are used in forensics for personal identification.

2. A unique sequence of nucleotides in a gene, used to identify specific organisms or individuals.

See: illustration

fingerprint

1. The unique pattern printed by the ridges of epidermis on the pulpy surfaces of the ends of the fingers and thumbs.

2. Of a protein, the pattern of fragments exposed by electrophoresis after splitting with a proteolytic enzyme such as trypsin.

3. Of DNA, a patterns of varying-length (polymorphic) restriction fragments that differs from one individual to another and that can be used as a means of unique identification.

4. Of a protein, the pattern of fragments produced on a plane surface when a protein is digested by a protein-splitting enzyme. See also DNA FINGERPRINTING.
