The component present in both nucleotides, and nucleosides is

• A. Sugar
• B. Phosphate
• C. Nitrogenous base
• D. Both (a) and (c)

Answer 1

The correct option is D Both (a) and (c)

Nucleoside is compound formed by the union of a nitrogen base with a pentose sugar. It is a component of nucleotide. Each nucleotide is composed of three units; a 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.
