Dear student

You need to understand that there are two different terms: Nucleoside and Nucleotide. Nucleoside is a structure which has Nitrogenous base+ Pentose sugar
Nucleotide is a structure which hasNitrogenous base+ Pentose sugar+ Phosphate.
So basically nuceloside has no phosphate group but nucleotide has a phosphate group. Their nomenclature is as follows:
