Deoxyribonucleic acid (/ d iː ˈ ɒ k s ɪ ˌ r aɪ b oʊ nj uː ˌ k l iː ɪ k,-ˌ k l eɪ-/ ⓘ; [1] DNA) is a polymer composed of two polynucleotide chains that coil around each other to form a double helix. The polymer carries genetic instructions for the development, functioning, growth and reproduction of all known organisms and many ...
Pronunciation follows convention outside the medical field, in which acronyms are generally pronounced as if they were a word (JAMA, SIDS), initialisms are generally pronounced as individual letters (DNA, SSRI), and abbreviations generally use the expansion (soln. = "solution", sup. = "superior").
Deoxyribonucleic acid (DNA) is a nucleic acid containing the genetic instructions used in the development and functioning of all known living organisms. The chemical DNA was discovered in 1869, but its role in genetic inheritance was not demonstrated until 1943. The DNA segments that carry this genetic information are called genes.
Daily News and Analysis, an Indian broadsheet newspaper between 2005 and 2019; DNA, an American science fiction action film; DNA, a French drama film; DNA (British TV series), a British television crime drama, aired in 2004 and 2006
This is still the general rule. But for certain classes of abbreviations or acronyms (such as clinical trial acronyms [e.g., ECOG] or standardized polychemotherapy regimens [e.g., CHOP]), this pattern may be reversed, because the short form is more widely used and the expansion is merely parenthetical to the discussion at hand. The same is true ...
The word acronym is formed from the Greek roots akro-, meaning 'height, summit, or tip', and -nym, 'name'. [6] [unreliable source] This neoclassical compound appears to have originated in German, with attestations for the German form Akronym appearing as early as 1921. [7]

The nucleic acid notation currently in use was first formalized by the International Union of Pure and Applied Chemistry (IUPAC) in 1970. [1] This universally accepted notation uses the Roman characters G, C, A, and T, to represent the four nucleotides commonly found in deoxyribonucleic acids (DNA).
