RNA nucleotides contain three components:A Nitrogenous BaseA Five-Carbon SugarA Phosphate GroupRNA nitrogenous bases includeadenine (A),guanine (G),cytosine (C)anduracil (U). The five-carbon (pentose) sugar in RNA is ribose. RNA molecules arepolymersof nucleotides joined to one another by covalent bonds between the phosphate of one nucleotide and the sugar of another. These linkages are called phosphodiesterlinkages.
