Question

25. Given the details of N bases with the molecular structure.
​

Answer 1

Answer:

A nitrogenous base, or nitrogen-containing base, is an organic molecule with a nitrogen atom that has the chemical properties of a base. The main biological function of a nitrogenous base is to bond nucleic acids together. A nitrogenous base owes its basic properties to the lone pair of electrons of a nitrogen atom.

Adenine

Thymine

Guanine

Cytosine

Uracil

Nitrogenous bases are typically classified as the derivatives of two parent compounds, pyrimidine and purine.[1] They are non-polar and due to their aromaticity, planar. Both pyrimidines and purines resemble pyridine and are thus weak bases and relatively unreactive towards electrophilic aromatic substitution.[2]
