DNA fingerprinting. View of gloved hands holding a ruler to measure human DNA fingerprints. The DNA fingerprint is seen as a pattern of bands in the background. The banding pattern produced is unique to each individual, which forms a kind of genetic "identity card". In humans this DNA genetic material, found in the nucleus of each cell, is usually extracted from white blood cells, sperm or hair follicles. By analysing the banding pattern, DNA fingerprints are used to prove conclusively whether people are related, for instance in immigration or paternity disputes. The technique is also used to identify criminals.
