What did he do?
•
Sir Alec Jeffreys is a geneticist who
first developed DNA fingerprinting
techniques those of which are
commonly used today for police
and detective work, paternity tests,
and immigration issues
DNA Profiling
• DNA Profiling is a system employed by
forensic scientists that allows each
recorded person to be identified using
their genotypes
• Each person has different DNA in their
body, so this is a way of differentiating
each and every person by simply studying
and analyzing his/her DNA
DNA Fingerprinting
•
•
•
•
One day after the research for DNA profiling
was completed for its first installment,
Jeffreys and his team to a look at a gene, the
Myoglobin Gene.
This Gene is located on your fingerprint
After gaining the location of the Muoglobin
Gene, Jeffreys created new clear Fingerprints
that Showed Clean DNa Patterns and Genes.
This was A Huge Success for Morden
Science.
His “In the Field” Work
• After discovering the technique of genetic fingerprinting at the University of Leicester, he
continued to work there as a professor in the Department of Genetics.
• Sir Alec Jeffreys's methods were soon applied to the public when two young women were
raped and murdered in Leicestershire.
• One man was arrested for admitting to the murder of one of the women but not the other.
Suspected of murder for both women, DNA samples were taken from him and the victim's
bodies.
• Shockingly, he was found innocent of both. DNA samples were then taken on every male in
the area but no match was found.
Finally
•
•
Then a man named Colin Pitchfork was
overheard boasting about how he got away with
his friend lending him a sample of his DNA. He
was then found guilty and the case was solved In
1986, thanks to Jeffrey's contributions to science.
He still lives today and continues his work on
DNA Profiling and Fingerprinting at the age of 62
