, Oxfordshire, England. He came from a middle-class family and has one brother and sister. He spent the first six years of his life in Oxford until 1956 when the family moved to Luton. His curiosity and inventiveness were probably gained from his father, as well as his paternal grandfather who had a number of patents to his name. When he was eight years old his father gave him a large chemistry set

Jeffreys' DNA method, which is often called DNA fingerprinting, was first put to use when he was asked to help in a disputed immigration case to confirm the identity of a British boy whose family was originally from Ghana

. The case was resolved when the DNA results proved that the boy was closely related to the other members of the family, and Jeffreys saw the relief in the mother's face when she heard the results. DNA fingerprinting was first used as a police forensic test to identify the rapist and killer of two teenagers, Lynda Mann and Dawn Ashworth, who were both murdered in Narborough, Leicestershire

 samples taken from the two dead girls. This turned out to be a specifically important identification for without it, British Authorities believe that Richard Buckland, the main suspect, would have inevitably been convicted. Therefore, not only did Jeffrey's work in this case prove who the real killer was, but exonerate someone who likely would have spent his life in prison otherwise. In 1992, Jeffreys' methods were used to confirm the identity for German prosecutors of the Nazi Dr. Josef Mengele

 bone of his exhumed skeleton, and DNA from his widow and son, in a similar way to paternity testing.

DNA profiling

DNA profiling based on typing individual highly variable minisatellites in the human genome was also developed by Alec Jeffreys and his team in 1985, with the term DNA fingerprinting being retained for the initial test that types many minisatellite

 (NDNAD) in 1995. With highly automated and sophisticated equipment, modern-day DNA profiling can process hundreds of samples each day. Ten microsatellites plus a marker for sex determination are used with the current system developed for the NDNAD, giving a discrimination power of one in over a billion. Under British law, anyone arrested in England, Wales or Northern Ireland has their DNA profile taken and stored on the database whether or not they are convicted (different rules apply in Scotland). The national database now contains the DNA information of nearly five million people. Jeffreys has opposed the current use of DNA profiling, where the government has access to that database, and has instead proposed a database of all people's DNA, whose access would be controlled by an independent third party.

Personal life

Jeffreys married Sue (née Miles) on 28 August 1971, and they have two daughters, born in 1979 and 1983. Their two daughters were still very young and growing up when Jeffreys' work life became hectic for the two or three years following his genetic fingerprinting breakthrough.
