Question

What type of bond connects a nitrogenous base to the pentose sugar in a nucleotide?

Options

• Phosphodiester bond

• N-glycosidic bond

• Hydrogen bond

• Ester bond

Answer 1

The nitrogenous base is attached to the pentose sugar through an N-glycosidic bond. This bond forms between the nitrogen atom of the base and the C1′ (1′ carbon) of the pentose sugar, creating the nucleoside structure.
