- Definition "single-stranded nucleic acid polymer of the four nucleotides adenine (A), cytosine (C), guanine (G), and uracil (U) joined through a backbone of alternating phosphate and ribose sugar residues" Reference "COM-Terminology Coordination, based on:'Ribonucleic acid (RNA)' (25.5.2020) Encyclopaedia Britannica."
- Comment "1) RNA is a single-stranded nucleic acid polymer of the four nucleotides A, C, G, and U joined through a backbone of alternating phosphate and ribose sugar residues. It is the first intermediate in converting the information from DNA into proteins essential for the working of a cell. Some RNAs also serve direct roles in cellular metabolism. RNA is made by copying the base sequence of a section of double-stranded DNA, called a gene, into a piece of single-stranded nucleic acid. This process, called transcription (see below RNA metabolism), is catalyzed by an enzyme called RNA polymerase.2) The RNA of RNA viruses has a dual function: it represents the genome of the viruses (formally analogous to DNA) and may, in part, serve itself as messenger."

- Definition "L'acide ribonucléique (ARN) est un polymère similaire à l'ADN [ IATE:778511 ], aussi bien en terme structurel qu'en terme fonctionnel (matérialisation et traitement de l'information génétique). Il y a quatre différences par rapport à l'ADN : a) le sucre désoxyribose est remplacé par un ribose; b) la base thymine est remplacée par un uracile ; c) l'ARN est généralement simple brin, sauf chez quelques organismes tels les rétrovirus; et d) l'ARN est court" Reference "Wikipédia, l'encyclopédie libre, http://fr.wikipedia.org/wiki/Acide_ribonucl%C3%A9ique [14.2.2007]"
