nu·cle·ic acid

 (no͞o-klē′ĭk, -klā′-, nyo͞o-)
n.
Any of a class of large molecules that are polymers of nucleotides and are found in all living organisms and viruses. The principal nucleic acids, DNA and RNA, are the carriers of hereditary information and control the synthesis of proteins.

nucleic acid

(njuːˈkliːɪk; -ˈkleɪ-)
n
(Biochemistry) biochem any of a group of complex compounds with a high molecular weight that are vital constituents of all living cells. See also RNA, DNA

nu•cle′ic ac′id

(nuˈkli ɪk, -ˈkleɪ-, nyu-)
n.
any of a group of long, linear macromolecules, either DNA or various types of RNA, that carry genetic information directing all cellular functions: composed of linked nucleotides.

nu·cle·ic acid

(no͞o-klē′ĭk)
Any of a group of organic compounds found in living cells and viruses that control the hereditary material of a cell or virus by regulating the synthesis of proteins. The two main nucleic acids are DNA and RNA.
