1985 Genetic fingerprinting enters the court room ‘DNA fingerprinting,’ was first described in 1985 by an English geneticist named Alec Jeffreys. Dr Jeffreysfound that certain regions of DNA contained DNA sequences that were repeated over and over again next to each other. He also discovered that the number of repeated sections present in a sample could differ from individual to individual. By developing a technique to examine the length variation of these DNA repeat sequences, Dr Jeffreys created the ability to perform human identity tests. http://www.harcourt-international.com/e-books/viewbook.cfm?ID=98
