adenine a definition
adenine ad·e·nine (ād'n-ēn', -ĭn) n. Abbr. A A purine base that is a constituent of DNA and RNA and an important energy transport and storage component in cellular metabolism. Adenine definition, Biochemistry. a purine base, C 5 H 5 N 5 , one of the fundamental components of nucleic acids, as DNA, in which it forms a base pair with thymine, and RNA, in which it pairs with uracil. Symbol: A. See more. (ād'n-ēn') A purine base that is a component of DNA and RNA, forming a base pair with thymine in DNA and with uracil in RNA. Adenine is also part of other biologically important compounds, such as ATP, NAD, and vitamin B-12, and occurs in tea. Chemical formula: C5H5N5. In DNA, the code letters are A, T, G, and C, which stand for the chemicals adenine, thymine, guanine, and cytosine, respectively. In DNA base pairing, adenine always pairs with thymine, and guanine always pairs with cytosine. Adenine is also one of the bases in RNA. There it always pairs with uracil (U). Adenine (Science: biochemistry) a nitrogenous base, one member of the basepair a-T . (biochemistry)Purine base found in dna paired with thymine, in rna paired with uracil. Adenine is one of the bases that form part of a nucleotide, the structures that are present in dna chains. Retrieved from https://www.biology-online.org/dictionary/index.php?title=Adenine&oldid=71277 adenine and guanine are constituents of all nucleic acids (see below) and, hence, are found in all plant and animal tissues. Each chromosome is made up of a molecule of DNA in the shape of a double helix which is composed of four chemical bases represented by the letters A (adenine), T (thymine), G (guanine) and C (cytosine). Medical Definition of A (adenine) A (adenine): In genetics, A stands for adenine, one member of the A-T (adenine-thymine) base pair in DNA. The other base pair in DNA is G-C (guanine-cytosine). Each base pair forms a rung of the DNA ladder. A DNA nucleotide is made of a molecule of sugar, a molecule of phosphoric acid, and a molecule called a base. Definition of guanine. : a purine base C5H5N5O that codes genetic information in the polynucleotide chain of DNA or RNA — compare adenine, cytosine, thymine, uracil. A purine base that is a component of DNA and RNA, forming a base pair with thymine in DNA and with uracil in RNA. Adenine is also part of other biologically important compounds, such as ATP, NAD, and vitamin B-12, and occurs in tea. Chemical formula: C 5 H 5 N 5.
