  2. Biography • Professor Sir Alec J Jeffreys was born on January 9, 1950 in England. • He went on to study genetics and biochemistry at Oxford, and then in 1977 he went to the University of Leicester. • He and his colleagues tried to concentrate on “mini-satellite” sections of dna because they made better markers for tracking positions of genes. • In 1984, Sir Alec Jeffreys became known for his development of genetic fingerprinting, or analyzing the unique patterns found in DNA to determine an individual’s identity. • In 1987, Jeffreys was appointed professor of genetics.

  3. Relation to Forensics • The use of DNA fingerprinting is widely appreciated in many aspects of life. It can solve paternity dilemmas. This method also is helpful in solving crimes and disputes in immigration cases. • Sir Alec Jeffreys was also the creator of DNA , which and his team developed in 1985. This technique used specific parts of the fingerprints and was much better suited for using computers as a database to store information. • Jeffrey’s discoveries helped solve a murder case that would have been very difficult to solve without the use of DNA. This was the first time the science was used this way.

  4. Relation to Forensics • Jeffreys’ technique was used to solve a criminal case for the first time in 1986, when it was used to convict a rapist and killer of two girls in Leicestershire. • His development has also been used many times to exonerate suspects wrongly accused. It also helped prove that “Dolly” the sheep was the world’s first cloned mammal. • For his works and discoveries in genetics, Alec Jeffreys became Sir Alec Jeffreys in 1994 when he was knighted by Queen Elizabeth II.
