In 1984, Alec Jeffreys produced the first DNA fingerprint. DNA-based testing methods have evolved over the years, but they still use DNA repeats as the basis for building a DNA profile.
How a DNA fingerprint like this was made.
Alec Jeffreys talks about how he came up with the name.
DNA fingerprints are also known as DNA profiles. They are now made using probes that detect differences in the number of short tandem repeats (STRs) between individuals.
Alec Jeffreys (the "inventor" of DNA fingerprinting) explains repeats.
A laboratory that specializes in DNA fingerprint testing extracted DNA from a semen sample, E(vs), retrieved from Perry's body, and blood samples from Reesh, S1, and Jones, S2. The lab used a cocktail of single-locus probes to produce the DNA fingerprint
