The Structure of Tobacco Rattle Virus Ribonucleic Acids: Nature of the 3'-Terminal Nucleosides

The two species of RNA have been purified from the long and short particles of the multicomponent plant virus, tobacco rattle isolate CAM. 3'-End-group analysis, using the technique of periodate oxidation followed by reduction with [³H]-borohydride, showed that both species of RNA had an unphosphorylated cytidine residue at the 3' end.
