DNA ANALYSIS TECHNIQUES

Abstract

The DNA analysis techniques that make it possible to identify a suspect using a person’s unique genetic blue print have only been around since 1985. That's when Alec Jeffreys and his colleagues in England first demonstrated the use of DNA in a criminal investigation. Since then, DNA evidence has played a bigger and bigger role in many nations' criminal justice systems. It has been used to prove that suspects were involved in crimes and to free people who were wrongly convicted.
