Answer

D

Explanation

Nucleoside is a compound formed by the union of a nitrogen base with a pentose sugar. It is a component of nucleotid. Each nucleotide is compound of three units, a nitrogen base, a pentose sugar and a phosphate group nitrogen base, a pentose sugar and a phosphate group.

The nucleoside combines with a phosphate group at `5'` position by an ester bond to form a nucleotide or nucleoside monophosphate.
