Phosphodiester
DNA and RNA nucleotides are made up of a ribose sugar group, a nitrogenous base (either cytosine, guanine, adenine, thymine or uracil) and a phosphate group. The backbone of DNA and RNA strands are formed when many nucleotides are stacked on top of each other. Phosphodiester bonds form between the 3' hydroxyl group of the sugar of one nucleotide and the 5' phosphate group another allowing the construction of large chains which hold vast amounts of genetic information.
