Adenine (/ ˈ æ d ɪ n iː n /, / ˈ æ d ɪ n ɪ n /) (symbol A or Ade) is a purine nucleotide base. It is one of the nucleobases in the nucleic acids, DNA and RNA. The shape of adenine is complementary to either thymine in DNA or uracil in RNA. In cells adenine, as an independent molecule, is rare.
In DNA, the amount of guanine is equal to cytosine and the amount of adenine is equal to thymine. The A:T and C:G pairs are structurally similar. The A:T and C:G pairs are structurally similar. In particular, the length of each base pair is the same and they fit equally between the two sugar-phosphate backbones.
Nucleobases such as adenine, guanine, xanthine, hypoxanthine, purine, 2,6-diaminopurine, and 6,8-diaminopurine may have formed in outer space as well as on earth. [ 7 ] [ 8 ] [ 9 ] The origin of the term base reflects these compounds' chemical properties in acid–base reactions , but those properties are not especially important for ...
The four bases found in DNA are adenine (A), cytosine (C), guanine (G) and thymine (T). These four bases are attached to the sugar-phosphate to form the complete nucleotide, as shown for adenosine monophosphate. Adenine pairs with thymine and guanine pairs with cytosine, forming A-T and G-C base pairs. [17] [18]
Nucleosides are glycosylamines that can be thought of as nucleotides without a phosphate group.A nucleoside consists simply of a nucleobase (also termed a nitrogenous base) and a five-carbon sugar (ribose or 2'-deoxyribose) whereas a nucleotide is composed of a nucleobase, a five-carbon sugar, and one or more phosphate groups.
Adenosine monophosphate (AMP), also known as 5'-adenylic acid, is a nucleotide.AMP consists of a phosphate group, the sugar ribose, and the nucleobase adenine.It is an ester of phosphoric acid and the nucleoside adenosine. [1]
