What Does DNA Mean in a Text?

DNA means "Deoxyribonucleic Acid," "Does Not Apply," and "Did Not Attend." Here is more information about each of these definitions of DNA.

Deoxyribonucleic Acid

DNA, or deoxyribonucleic acid, is the hereditary material found in cells of all living organisms. It is inherited from parents - half from the mother, and half from the father - and determines everything from eye color to immune system. The discovery of DNA is credited to James Watson and Francis Crick, in 1953.

DNA consists of two strands of nucleotides twisted into a double helix. Each nucleotide contains a sugar, a phosphate, and one of four nitrogenous bases: adenine (A), cytosine (C), guanine (G), and thymine (T). The sequence of these bases encodes genetic instructions for making proteins and governing biological functions.

Does Not Apply

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 could write DNA.

In this context, DNA means the same as the more commonly used N/A, meaning "Not Applicable."

Did Not Attend

DNA may also mean "Did Not Attend," which indicates that someone was not present at an event.
