In DNA and RNA, a nitrogenous base forms a bond with a 5-sided carbon sugar molecule, which forms a “backbone” for the entire molecule. A nitrogenous base plus this sugar backbone is known as a nucleotide, and forms the building blocks of DNA and RNA.
Nitrogen base definition: a nitrogen-containing organic compound that has the chemical properties of a base, especially a pyrimidine or purine. See examples of NITROGEN BASE used in a sentence.
A nitrogenous base is an organic molecule that contains the element nitrogen and acts as a base in chemical reactions. The basic property derives from the lone electron pair on the nitrogen atom.
A nucleotide is composed of a nitrogenous base, deoxyribose (five-carbon sugar), and at least one phosphate group. The nitrogenous bases are purines such as adenine (A) and guanine (G), or pyrimidines such as cytosine (C), thymine (T), and uracil (U).
The meaning of NITROGEN BASE is a nitrogen-containing molecule with basic properties; especially : one that is a purine or pyrimidine.
A nitrogenous base is a molecular component of nucleic acids that contains nitrogen and acts as a fundamental building block for DNA and RNA. These bases are essential for encoding genetic information, pairing through hydrogen bonds, and contributing to the overall structure of nucleic acids.
Definition. Nitrogenous bases are the fundamental building blocks of nucleic acids like DNA and RNA, consisting of nitrogen-containing molecules that play a crucial role in storing and transmitting genetic information.
A nitrogenous base is a type of organic compound that contains at least one nitrogen atom and is capable of accepting a proton to form a positively charged ion. These bases are essential components of nucleic acids, such as DNA and RNA, and play a crucial role in various biological processes.
A nucleotide is an organic molecule made of a nitrogenous base, pentose sugar, and phosphate group. Nucleotides are ubiquitous in biology, serving as the foundation of genetic material and fulfilling other essential roles in cells. Take a look at what a nucleotide is, its structure, and its function in biological processes.
The nitrogenous bases are planar aromatic heterocyclic ring compounds which absorb ultraviolet light. They are of two different types, derived from pyrimidine and purine respectively. The structure of pyrimidine is shown below. It is a six-membered unsaturated ring compound containing four carbon and two nitrogen atoms.
