What was DNA fingerprinting first used for?
DNA fingerprinting was invented in 1984 by Professor Sir Alec Jeffreys after he realised you could detect variations in human DNA, in the form of these minisatellites. DNA fingerprinting is a technique that simultaneously detects lots of minisatellites in the genome to produce a pattern unique to an individual.
Why is DNA fingerprinting important and/or useful?

How does DNA fingerprinting affect society?
DNA fingerprinting is an integral part of today’s society. Since its discovery in the 1980s, DNA fingerprinting has become an extremely powerful tool to convict the guilty, or exonerate the innocent. It is often referred to as the greatest tool in the history of forensic science.
Why is DNA so important?
DNA is pivotal to our growth, reproduction, and health. It contains the instructions necessary for your cells to produce proteins that affect many different processes and functions in your body. Because DNA is so important, damage or mutations can sometimes contribute to the development of disease.
Are fingerprints part of DNA?
It has been proven that DNA can be obtained even from a single fingerprint. However, there are several problems linked to a fingerprint sample as DNA source. One of the main problems associated with fingerprints is that only 30-35 % of fingerprints have been successfully amplified and typed.
Is DNA better than fingerprints?
In crime scenes where biological evidence was collected and tested, DNA evidence was five times more likely than fingerprints to yield a suspect and nine times more likely to lead to an arrest. …
