Nucleoside	Nucleotides
1. A nucleoside consists of a nitrogenous base covalently attached to a sugar (ribose or deoxyribose) but without the phosphate group.	1. A nucleotide consists of a nitrogenous base, a sugar (ribose or deoxyribose) and one to three phosphate groups.
2. Several nucleoside analogues are used as antiviral or anticancer agents.	2. Malfunctioning nucleotides are one of the main causes of all cancers known of today.
3. Nucleoside = Sugar + Base	3. Nucleotide = Sugar + Base + Phosphate
4.Examples of nucleosides include cytidine, uridine, adenosine, guanosine, thymidine and inosine.	4. Nucleotides follow the same names as nucleosides, but with the indication of phosphate groups. For example, 5'-uridine monophosphate.

Nucleiside A nucleoside consists simply of a nucleabase ( also termed a nitrogenous base) & a five-carbon sugar (either ribose or deoxyibase), whereas a nucleabase, a five - carbon sugar & one or more phosphate group. Nucleotide A nucleotide is one of the structural component or building blocks, of DNA & RNA. A nucleotide consists of a base (one of four chemicals: Adenine, thynine, guanine & cytosine ) plus a molecular of sugar & one of phosphoric acid.
