What Does DNA Mean?


DNA means “Deoxyribonucleic Acid”. The abbreviation DNA stands for “deoxyribonucleic acid,” which is the biological instructions that make every species unique. DNA is inherited from parents – half from the mother, and half from the father – and determines everything from eye colour to immune system.

DNA was first used in 1986 in the criminal prosecution of a 17-year-old alleged rapist. The tests proved the teenager was in fact not the perpetrator and the actual attacker was eventually caught, also using DNA testing.

The abbreviation DNA can also mean “Does Not Apply”, meaning something is not applicable. For example, if a document asks for a spouse’s name, but you are single, you would write DNA, sometimes written as N/A meaning “Not Applicable”.
