The nitrogenous bases that form DNA and RNA are classified as pyrimidine and purine bases. 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. Meaning of NITROGENOUS BASE. double helix Fig. 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. Purines are derived from pyrimidines by addition of an imidazole group. 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: ( 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. The term is used especially of organic ring compounds, such as adenine, guanine, cytosine, and thymine, which are constituents of nucleic acids. 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. Definition of NITROGENOUS BASE in the Definitions.net dictionary. A nitrogenous base, such as cytosine, thymine, or uracil, with a characteristic single-ring structure; one of the components of nucleic acids. nitrogenous base A basic compound containing nitrogen. The nitrogenous bases are paired in specific combinations: adenine with thymine and guanine with cytosine. 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.
