Answer:

                Difference between a nucleotide and nucleoside is as follows              

Nucleoside	Nucleotide
Nucleoside is a compound formed by the union of the nitrogenous base with a pentose sugar It is slightly basic in nature It is a component of nucleotide and forms with both ribose and deoxyribose sugars. e.g., cytidine, uridine, adenosine, guanosine, thymidine and inosine.	Nucleotide is compound formed by union of nitrogen base, a pentose sugar and phosphate. A nucleotide is acidic in nature Nucleotide is formed through phosphorylation ofnucleoside e.g., AMP, GMP, CMP, UMP, dTMP (deoxythymidine monophosphate) 0
