A white, finely crystalline alkaloid, usually obtained from tea by extraction or from uric acid by synthesis, used chiefly in medicine. One of four nucleotides which are the primary bulling blocks for DNA.
A chemical that is a basic structural unit of a living thing's DNA. It is one of 4 key bases or nucleotides (cytosine (C), guanine (G) and thymine (T)) that repeat throughout the length of a DNA chain. In groups or sequences they form genes. Each human cell contains roughly 6 million G's, A's, T's and C's. A typical small gene can be made up of 3000 pairs of these bases, even more.
One of the four nitrogen-containing bases occurring in nucleotides, the building blocks of the organic macromolecule group known as nucleic acids (DNA and RNA). Adenine is also the base in the energy carrying molecule ATP (adenosine triphosphate) which is the energy coin of the cell. PICTURE

The bases found in DNA come in four varieties: adenine, cytosine, guanine, and thymine—often abbreviated as A,C, G, T, the letters of the genetic alphabet. (IOCeleraGenome) Adenina Essas letras são as iniciais dos nomes de quatro bases nitrogenadas: adenina (A), timina (T), citosina (C) e guanina (G). (POPrGenoma)
One of the four bases found in DNA, having the double-ring structure of a class known as purines. Adenine always forms complementary base paring with a DNA pyrimidine base called thymine. When pairing with RNA during transcription, adenine is complementary to uracil. Adenine also occurs in RNA molecules.
Adenine is a purine with a variety of roles in biochemistry including cellular respiration, in the form of both the energy-rich adenosine triphosphate (ATP) and the cofactors nicotinamide adenine dinucleotide (NAD) and flavin adenine dinucleotide (FAD), and protein synthesis, as a chemical component of DNA and RNA.
