A nitrogenous (nitrogen-containing) base is a nitrogen-containing molecule having the chemical properties of a base. It is an organic compound that owes its property as a baseto the lone pair of electrons of a nitrogen atom. In biological sciences, nitrogenous bases are typically classified as the derivatives of two parent compounds, pyrimidine and purine.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. Their flat shape is particularly important when considering their roles in nucleic acids as nucleobases (building blocks of DNA and RNA): adenine, guanine,thymine, cytosine, and uracil. These nitrogenous bases hydrogen bond between opposing DNA strands to form the rungs of the "twisted ladder" or double helix of DNA or a biological catalyst that is found in the nucleotides. Adenine is always paired with Thymine, and Guanine is always paired with Cytosine.
A nitrogenous base consists of a nitrogen-containing molecule with a cyclic structure. It typically includes a nitrogen atom that can form hydrogen bonds with another nitrogenous base, a sugar molecule, and a phosphate group. The four types of nitrogenous bases found in DNA are adenine, thymine, cytosine, and guanine.

Which is a single-ringed nitrogenous base?
Adenine is a single-ringed nitrogenous base found in DNA and RNA molecules.
Which element is not a part of a nitrogenouse base?
phosphorus
Is phosphorus part of the nitrogenous base?
No, phosphorus is not part of the nitrogenous base. The nitrogenous bases in DNA are adenine, thymine, cytosine, and guanine, which contain nitrogen atoms but not phosphorus. Phosphorus is primarily found in the sugar-phosphate backbone of the DNA molecule.
What is made up of three parts a deoxyribose sugar a phosphate group and a nitrogenous base?
nucleotides that are the building blocks of nucleic acids are made up of sugar, a nitrogen base and phosphate group
What are the Three components of a DNA molecule?
A sugar (deoxyribose), a phosphate group, and a nitrogenous base (adenine, thymine, cytosine or guanine). P, O, C, N, H, (and some associated metal ions, though not technically necessary to make up DNA).
What are parts of a nucleotid?
Nucleotides are made up of three parts. These parts are pentose sugars, phosophate groups and nitrogenous base.
