Phosphodiester bond: The chemical linkage connecting nucleotide monomers in DNA and RNA, consisting of a phosphate group bonded to two esterified hydroxyl groups.

Ribozymes are essentially RNA molecules that are capable of catalyzing a chemical reaction. Many naturally occurring ribozymes either catalyze the hydrolysis of their own phosphodiester bonds or ...

Ribonucleic acid (RNA) is a linear molecule composed of four types of smaller molecules called ribonucleotide bases: adenine (A), cytosine (C), guanine (G), and uracil (U).
