PDF | Nucleotide and nucleoside are building blocks of nucleic acids. draw the general structure of a nucleotide and a nucleoside. This form is called C-nucleoside vs traditional N-nucleoside forms. Nucleotides are building blocks of nucleic acids (DNA and RNA). A nucleoside consists simply of a nucleobase (also termed a nitrogenous base) and a five-carbon sugar (ribose or 2'-deoxyribose) whereas a nucleotide is composed of a nucleobase, a five-carbon sugar, and one or more phosphate groups. The nitrogenous base can be any nitrogenous base depending upon the kind of nucleoside to be developed. This is because nucleotides are the building blocks of nucleic acids and certain nucleotides serve as the energy currency of the cell. While only nucleotides exhibit a major in vivo biological function, nucleosides present in vitro applications. The file may contain a single sequence or a list of sequences.
