DNA fingerprinting definition

A technique by which the DNA of an individual can be compared with that found in a sample or another individual. It differs from DNA sequencing in that it compares only a few features of two strands of DNA.

Note: DNA fingerprinting is accepted as evidence in criminal trials, as well as in courts for establishing paternity and in identifying remains.
