DNA Fingerprinting Is 25 Years Old

Today marks the 25th anniversary of DNA fingerprinting.

The technique was discovered by Professor Sir Alec Jeffreys at Leicester University (UK):
"Apart from identical twins, it is widely agreed that no two people have the same DNA fingerprint. As such a fingerprint from a sample at a crime scene can be compared to a suspect’s, and if there is a match, the evidence against them is very strong (...)"

"Professor Jeffreys’s discovery has not only benefited forensic science, but has enabled the tracking of historical migration of groups, and revealed family ties for children whose parentage is unknown."
