DNA IDENTIFICATION
DNA identification.A method of scientific identification based on a person’s unique genetic
makeup; specif., the comparison of a person’s deoxyribonucleic acid (DNA) — a patterned
chemical structure of genetic information — with the DNA in a biological specimen (such as
blood, tissue, or hair) to determine whether the person is the source of the specimen. • DNA
evidence is used in criminal cases for purposes such as identifying a victim’s remains, linking a
suspect to a crime, and exonerating an innocent suspect. — Also termed DNA fingerprinting;
genetic fingerprinting; DNA profiling; DNA typing. Cf. HUMAN-LEUKOCYTE ANTIGEN
