WebNitrogenous bases are organic molecules that contain a ring structure that includes both carbon and nitrogen atoms and can act as a base in chemical reactions. The lone pair of electrons on one of the nitrogen atoms acts as a Lewis base, able to donate a pair of electrons in a chemical reaction. Web21 de dez. de 2024 · Answer: The nitrogenous bases are complementary to each other which means the complementary bases will bind with each other.
