DNA Fingerprinting
An individual's entire DNA sequence is composed of over 3 billion nucleotides,. Although the sequence is about 99.9% the same as other humans, the remaining 0.1% about 3 million nucleotides is unique to that individual. As a result, with the exception of identical twins, who have identical DNA sequences, no human ever has exactly the same DNA as another one. This genetic distinctiveness can be a powerful tool in identifying persons, in much the same way as a person's unique fingerprint.
