Ansanm ak ADN, RNA gen ladan asid yo nukleik, ki, ansanm ak pwoteyin, konstitye twa makromolekil yo pi gwo esansyèl pou tout fòm li te ye nan lavi yo. Menm jan ak ADN, RNA reyini kòm yon chèn nikleodid, men anjeneral yon sèl bloke. Òganis selilè sèvi ak mesaje RNA (mRNA) pou transmèt enfòmasyon jenetik (souvan note ki itilize lèt G., A, U, ak C pou nukleotid guanine, adenin, uracil ak sitozin) ki dire sentèz pwoteyin espesifik, pandan ke anpil viris kode jenetik yo enfòmasyon lè l sèvi avèk yon jenomi RNA.

Together with DNA, RNA comprises the nucleic acids, which, along with proteins, constitute the three major macromolecules essential for all known forms of life. Like DNA, RNA is assembled as a chain of nucleotides, but is usually single-stranded. Cellular organisms use messenger RNA (mRNA) to convey genetic information (often notated using the letters G, A, U, and C for the nucleotides guanine, adenine, uracil and cytosine) that directs synthesis of specific proteins, while many viruses encode their genetic information using an RNA genome.
