RNA


RNA
(= 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.
