(Abbreviation: A). One the bases found in DNA and RNA
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 nitrogenous bases in the nucleotides of DNA and RNA.
(= 6-aminopurine). One of the purine bases found in nucleic acids and nucleotides. In DNA, it always pairs with thymine (T).

a nitrogen-containing base found in DNA molecules. Pairs with thymine.
a nitrogenous base that is found in DNA and RNA. Its complimentary base is Thymine.
A nitrogen rich base which is one of the buiding blocks of DNA. It is one member of the base pair A-T (adenine-thymine) See also: Base Pair See also: Thymine
Adenine is the base that normally base-pairs with Thymine (T) in DNA.
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.

A purine base that is one of the building blocks of DNA. Adenine binds with thymine in DNA and with uracil in RNA.
A purine; one of the nitrogenous bases in the nucleic acids RNA and DNA.
A nitrogenous base, one member of the base pair AT (adenine-thymine).
A purine base; one of the four molecules containing nitrogen present in the nucleic acids DNA and RNA; designated by letter A.
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.
