RNA

n. large molecule found in all cells and similar in structure to DNA, molecule that plays a major role in protein synthesis and cellular chemical processes (Biology)

For other uses, see RNA (disambiguation). Ribonucleic acid or RNA is a nucleic acid polymer consisting of nucleotide monomers, which plays several important roles in the processes of translating genetic information from deoxyribonucleic acid (DNA) into proteins. RNA acts as a messenger between DNA and the protein synthesis complexes known as ribosomes, forms vital portions of ribosomes, and acts as an essential carrier molecule for amino acids to be used in protein synthesis.

Noun
1. (biochemistry) a long linear polymer of nucleotides found in the nucleus but mainly in the cytoplasm of a cell where it is associated with microsomes; it transmits genetic information from DNA to the cytoplasm and controls certain chemical processes in the cell; "ribonucleic acid is the genetic material of some viruses"
(synonym) ribonucleic acid
(hypernym) polymer
(hyponym) messenger RNA, mRNA, template RNA, informational RNA
(substance-meronym) ribose
(part-meronym) nucleic acid
(classification) biochemistry
