What is the difference between a nucleoside and a nucleotide?
A nucleoside is formed by the attachment of a base to the position of the sugar.
Nucleoside = Sugar + Base
On the other hand, all the three basic components of nucleic acids (i.e., a pentose sugar,
phosphoric acid, and base) are present in a nucleotide.
Nucleotide = Sugar + Base + Phosphoric acid
