ribonucleotide

 [ri″bo-noo´kle-o-tīd]
a nucleotide in which the purine or pyrimidine base is combined with ribose.

ri·bo·nu·cle·o·tide

(rī'bō-nū'klē-ō-tīd),
A nucleotide (nucleoside phosphate) in which the sugar component is ribose; the major ribonucleotides of RNA are adenylic acid, cytidylic acid, guanylic acid, and uridylic acid.
