| fingerprinting | The basic principle of the technique is to digest a large molecule with a sequence specific hydrolase to produce moderate size fragments that can then be run on an electrophoresis gel. Provided the hydrolase only cleaves at specific sites (e.g. Between particular amino acids or bases) then the fragments should be characteristic of that molecule. The technique can be used to distinguish strains of virus or to differentiate between similar but nonidentical proteins (peptide mapping). Not to be confused with footprinting. (18 Nov 1997) |

| genetic fingerprinting | The process of comparing the nucleotide sequences of different DNA samples to find out if the samples are from the same individual or not. This is often used as a way to investigate crime, for example by comparing samples found at the crime scene with samples from the suspects. (09 Oct 1997) |

| fingerprinting |
a technique for determining the structure of a protein in which the protein is split into peptides by digestion with a protease and the fragments are separated in one direction by electrophoresis and at right angles by chromatography. After staining, the peptide fragments are seen to be in characteristic locations.
