(= ribonucleic acid) This molecular species has an informational role, a structural role and an enzymic role and is thus used in a more versatile way than either DNA or proteins. Considered by many to be the earliest macromolecule of living systems. The structure is of ribose units joined in the 3' and 5' positions through a phosphodiester linkage with a purine or pyrimidine base attached to the 1' position. All RNA species are synthesized by transcription of DNA sequences, but may involve post-transcriptional modification.

(Humans as organisms) (Ribonucleic acid) - it converts the genetic information stored in DNA into proteins
Ribonucleic acid, a polymer of the sugar ribose, phosphate, purine and pyrimidine bases which, as an adjunct to DNA, helps to transmit and implement the genetic instructions for protein synthesis carried on the DNA. Some viruses store their genetic information as RNA not as DNA.
Ribonucleic acid. Often found in viruses as the nucleic acid that caries the genome of the agent.
