DNA finger printing

DNA finger printing

dna finger printing is used by forensic scientists to help identify an individual based on their DNA profile

Although the vast majority of human DNA sequences are common in humans, DNA profiling makes use of highly variable repeat sequences, called variable number tandem repeats

The technique was first reported in 1985 by Sir Alec Jeffreys at the University of Leicester in England, and is now the basis of several national DNA databases.
