National DNA databaseIn 1995, the world's first national DNA database waslaunchedin England and Wales. New legislation gave police the authority to retain DNA samples from those previously arrested,. This enabled a revolutionary new tool to uniquely match suspects to crime scene evidence. Mouth swabs or hair samples being routinely collected were used for analysis. By 2005, 3 million profiles were held in the database. New Zealand followed on 12 Aug 1996, and subsequently other countries established their own national DNA databases. The technique for identifying individuals was discovered in 1984 byAlec Jeffreys, based on Restriction Fragment Length Polymorphism, and made practical when, in 1986, Kary Mullis created the Polymeraze Chain Reaction to replicate DNA for analysis.« |
