What is the difference between a nucleoside and a nucleotide? |
Answer» Nucleoside is formed by the condensation of a purine or pyrimidine base with pentose sugar at position 1. When nucleoside is linked to phosphoric acid at 5 position of sugar moiety, we get a nucleotide. Hence a nucleotide has three units – Phosphate group, pentose sugar and a base, whereas nucleoside has two units – pentose sugar and a base. |
