Answer:
Pyridine Nicotinamide
Explanation:
The nitrogen-containing bases of nearly all nucleotides are derivatives of three heterocyclic compounds: pyrimidine, purine, and pyridine. The most common nitrogen bases are the pyrimidines (cytosine, thymine, and uracil), the purines (adenine and guanine), and the pyridine nicotinamide.
NITROGENOUS BASES
Nucleotides are the building blocks of Nucleic acids (RNA and DNA). A nucleotide subunit is made of three components namely: nitrogenous base, five carbon sugar (ribose or deoxyribose) and a phosphate group.
Nitrogenous bases are of four kinds viz: adenine, guanine, cytosine, thymine/uracil. As the name implies, nitrogenous bases contain NITROGEN element in the core of their structure.
Therefore, nitrogenous bases are the components of nucleotides that contain NITROGEN.
