The technique of DNA fingerprinting was developed in 1984 by British geneticist Alec Jeffreys, after he noticed that certain sequences of highly variable DNA (known as minisatellites), which do not contribute to the functions of genes, are repeated within genes. In 1944, scientist Erwin Chargaff had read Oswald Avery's scientific paper, which identified DNA as the substance responsible for heredity. Nowadays, DNA typing is a widely used technique in the field of genetics. Dr. Alec J. Jeffreys in 1984 found out that there is a repeating sequences in the DNA known as VNTRs (variable number of tandem repeats) which can be seen as the bar code in the X-ray pictures.
