DNA Tests – DNA Profiling

Soon after the first DNA fingerprint was discovered, it wasn’t long until commercial DNA tests were born.

After Professor Jeffreys discovered purely by accident the DNA fingerprint in his laboratory in the 1980s, it quickly became an established tool for DNA profiling, DNA tests such as paternity tests and in the field of crime and forensics.

DNA Tests and DNA Profiling

When DNA profiling was being established, hundreds of cases such as identifying bodies, helping crime investigations and immigration court battles landed on the Professor’s desk. DNA tests were done to identify high profile bodies, such as the murdered bodies of Tsar Nicholas and his family and of the Nazi Josef Mengele. But it’s probably the world of crime that most captured the public’s imagination. And this has continued to the present day with crime shows such as CSI that feature DNA tests as routine in their fictional investigations to solve elaborate murder plots.

DNA Tests and Crime Scene Investigations

When two girls were raped and murdered in Leicestershire, Professor Jeffreys did the first ever DNA tests and DNA profiling for a forensic case. Although a man had said he killed one of the girls, the DNA tests proved he was innocent. As a result, samples were gathered from men in the local area near to the murders so DNA tests could be done to see if the samples matched those found on the victims. The killer was found and convicted and the reputation of DNA tests as a forensic tool established. There are thought to be around four million and rising DNA profiles on the national DNA database. Most of the profiles are convicted criminals or suspects – it means if investigators gather DNA samples from a crime scene, they can conduct DNA tests to see if the perpetrator is on the database. It’s possible to get an instant match – crime solved. Although civil liberty groups have expressed concerns about the database, Professor Jeffreys believes it to be the most powerful crime investigation tool around.
