What is the difference between Nucleotide and Nucleoside ?
A nuceoside is composed of two components of nucleic acids is a pentose sugar and a nitrogenous loss. It is formed when 1-position of the pyramidine or 9-position of purine is linked to of the sugar (ribase or deoxyribase) by a B-linkage . A nucleotide contains all the three basic components of nucleic acids i.e, a phosphoric acid group, a pentose sugar and a nitrogenous base formed by esterification of
of sugar of nucleoxide with phosphoric acid.
