A soup base is the flavoring or broth you use to get your soup started. base sequence: The order of nucleotide bases—A, T, G, C—in a sequence of DNA, which determines primary structure of the proteins encoded by that DNA. The base of something is usually the foundation, starting point, or main ingredient of something. Synonym Discussion of base. While ATP is widely recognized in a number of cellular reactions, it is not the only nitrogenous base that serves in cellular energy transfer.
The definition for the word base in biology terms is "The nucleobase of a nucleotide involved in base pairing, as of a DNA or RNA polymer." Base, in chemistry, any substance that in water solution is slippery to the touch, tastes bitter, changes the color of indicators (e.g., turns red litmus paper blue), reacts with acids to form salts, and promotes certain chemical reactions (base catalysis). Nitrogen base definition, a nitrogen-containing organic compound that has the chemical properties of a base, especially a pyrimidine or purine: Four nitrogen bases are present in a DNA molecule. There are 4 bases: adenine (A), guanine (G), thymine (T), and cytosine (C). home / medterms medical dictionary a-z list / base in dna definition Medical Definition of Base in DNA.
