Genetic fingerprinting: Sir Alec Jeffreys in conversation

Thirty years ago, the technique of genetic fingerprinting was invented here at the University of Leicester. It can be used to identify family relationships, or if DNA found belongs to a particular person. It has revolutionised the legal system and DNA evidence is now commonly used in criminal investigations. Recently, genetic fingerprinting was used to determine that the remains found in a car park in Leicester were indeed those belonging to King Richard III. Akanksha Bafna interviewed Professor Sir Alec Jeffreys before his retirement in September 2012, after nearly 40 years working at the University of Leicester.
