what are the differences between nucleoside and nucleotide ?
plzzzz answer as soon as possible
A nucleoside consists of a nitrogenous base covalently attached to a sugar (ribose or deoxyribose) but without the phosphate group. A nucleotide consists of a nitrogenous base, a sugar (ribose or deoxyribose) and one to three phosphate groups.
Nucleoside = Sugar + Base
Nucleotide = Sugar + Base + Phosphate
