Let’s break it down a bit to understand what the definition really means. Nitrogenous bases fall into the class of chemical compounds known as organic compounds or those which contain carbon. The SOP model of change as a new way of looking at causality Extending from each sugar molecule toward the center of the ladder is a nitrogenous base that is weakly bonded to a nitrogenous base extending from the opposing strand. 6.1 shows their chemical structure and the numbering of the elements in the molecule. What does NITROGENOUS BASE mean? Definition of NITROGENOUS BASE in the Definitions.net dictionary. 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 base to 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. Purines are derived from pyrimidines by addition of an imidazole group. nitrogenous base A basic compound containing nitrogen. In DNA nitrogenous bases are either pyrimidines or purines. Meaning of NITROGENOUS BASE. double helix Medical definition of nitrogen base: a nitrogen-containing molecule with basic properties; especially : one that is a purine or pyrimidine. The nitrogenous bases are paired in specific combinations: adenine with thymine and guanine with cytosine. Define nitrogen base. [1] The nitrogenous bases, meanwhile, occupy the interior portion of the molecule. nitrogenous: ( nī-troj'ĕ-nŭs ), Relating to or containing nitrogen. Information and translations of NITROGENOUS BASE in the most comprehensive dictionary definitions resource on the web. A nitrogenous base, such as cytosine, thymine, or uracil, with a characteristic single-ring structure; one of the components of nucleic acids. Critically, these bases are linked to each other with hydrogen bonds, forming the "rungs" of a structure that, if not wound into a helix, would resemble a ladder; in this model, the sugars and phosphates form the sides. A nitrogenous base is simply a molecule that contains nitrogen and has the chemical properties of a base. Nitrogenous bases.Nucleotide hydrolysis produces two types of substances derived from the heterocyclic rings purine and pyrimidine known as the purine and pyrimidine bases. Nitrogenous base carbon ring structure found in DNA or RNA that contains one or more atoms of nitrogen; includes adenine, guanine, cytosine, thymine, and uracil. The nitrogenous bases that form DNA and RNA are classified as pyrimidine and purine bases. Fig. nitrogen base synonyms, nitrogen base pronunciation, nitrogen base translation, English dictionary definition of nitrogen base. The term is used especially of organic ring compounds, such as adenine, guanine, cytosine, and thymine, which are constituents of nucleic acids.
