A nucleoside differs from a nucleotide. It lacks the

Options

A. base
B. suger
C. phophate group
D. hydroxyl group

Answer

C

Explanation

A nitrogenous base is attached to the pentose suger by an N-glycosidec linkage to from a nucleside, i.e., Nucleoside= Nitrogen base+Pentose suger
When a phosphate group is attached to the 5'-OH of a nucleoside through phosphodiester linkage, a nucleotide is formed , i.e., Nucleotide = Nitrogen base + Pentose suger + Phosphate `(PO_(4)`.
So, a nucleoside differs from a nucleotide as it lacks the phosphate group .
