The ribosomal and transfer ribonucleic acid (tRNA) fromMycoplasma mycoides var.capri , grown in a medium containing uridine-(14 C)-5′-triphosphate and cytidine-(5-3 H)-5′-triphosphate, were isolated and separated. The uridine in both species of RNA was shown to contain14 C and the cytidine to contain both3 H and14 C. Comparison of the labeling of 4-thiouridine and pseudouridine, obtained from an enzymatic digest of the RNA, indicates that their biosynthetic precursor is uridine, not cytidine. It is probable that ribothymidine and dihydrouridine have the same derivation.
