Adenine
Adenine (A) is one of four chemical bases in DNA, with the other three being cytosine (C), guanine (G), and thymine (T).
Nicotinamide adenine dinucleotide is a dinucleotide since it consists of two nucleotides joined by a pair of bridging phosphate groups.
Nicotinamide adenine dinucleotide (NAD) and its relative nicotinamide adenine dinucleotide phosphate (NADP) are two of the most important coenzymes in the cell.
Adenine A nitrogenous base, one member of the base pair A-T (adenine-thymine).
Alleles Alternative forms of a genetic locus; a single allele for each locus is inherited separately from each parent (e.g.
Adenine (A): A base; one of the molecular components of D NA and RNA. Bonds with thymine (A-T) in DNA, and with uracil (A-U) in RNA.
Alleles: Alternative forms of a genetic characteristic.
Adenine: A nitrogenous base. Pairs with thymine in DNA molecules.

Adenine (A)
Adenin is a purine base (nitrogenous base) and constituent of nulceotides and as such one member of the base pair A-T (adenine-thymine) in DNA and A-U (adenine-uracil) in RNA.
adenine A purine base; component of nucleotides and nucleic acids. A nitrogen base found in both DNA and RNA.
adenohypophysis An endocrine gland.
adenophorea The class of nematodes formerly called Aphasmidia. Examples: Trichinella, Trichuris.
An adenine-containing nucleoside triphosphate that releases free energy when its phosphate bonds are hydrolyzed. This energy is used to drive endergonic reactions in cells.

TATA box. An adenine- and thymine-rich promoter sequence located 25-30 bp upstream of a gene, which is the binding site of RNA polymerase.
A pair of complementary nitrogenous bases in a DNA molecule--adenine-thymine and guanine-cytosine. Also, the unit of measurement for DNA sequences. Bioaugmentation.
Base sequence -- a partnership of organic bases found in DNA and RNA; adenine forms a base pair with thymine (or uracil) and guanine with cytosine in a double-stranded nucleic acid molecule.
It is proposed that the adenine nucleotide translocase (ANT) is converted into a non-specific pore through a calciummediated conformational change.
DNA consists of four basic nucleotide sub-units, or bases, Adenine (A), Cytosine (C), Guanine (G), and Thiamine (T), linked together as a linear polymer. DNA, however, rarely occurs as a single polymer.
These nucleotides are composed of a nitrogenous base (A = adenine, T = thymine, C = cytosine, G = guanine) attached to a sugar called deoxyribose and the sugar is attached to a phosphate group which is negatively charged.
A subunit of DNA or RNA consisting of a nitrogenous base (purine in adenine and guanine, pyrimidine in thymine, or cytosine for DNA and uracil cytosine for RNA), a phosphate molecule, and a sugar molecule (deoxyribose in DNA and ribose in RNA).
The nucleoside containing adenine as its base.

(Adenosine TriPhosphate) A molecule consisting of adenosine (adenine plus a ribose sugar) and three phosphate groups.
Two nitrogenous (purine or pyrimidine) bases (adenine and thymine or guanine and cytosine) held together by weak hydrogen bonds. Two strands of DNA are held together in the shape of a double helix by the bonds between base pairs.
Included in this group are the nucleoside analogs, chemicals that are similar to one of the bases (adenine, cytosine, guanine, and thymine) that comprise DNA, but sufficiently different enough to block viral DNA synthesis.
Uracil is one of the four bases in RNA. The others are adenine, cytosine, and guanine. Uracil replaces thymine, which is the fourth base in DNA. Like thymine, uracil always pairs with adenine. [Talking Glossary]
