A nitrogenous base, one member of the base pair AT (adenine-thymine) See also: base pair, nucleotide
A nitrogen-containing, single-ring, basic pyrimidine that occurs in nucleotides of DNA and RNA The other pyrimidine in DNA is cytosine, and in RNA is uracil Thymine is one member of the base pair A-T (adenine-thymine)
one of the pyrimidine nucleic acid bases that make up nucleotides, the building blocks of DNA (but not RNA) The antiviral drugs AZT and d4T are nucleoside analogs associated with thymine
= One of the four nitrogenized bases, constituent fundamental of the nucleic acids
Organic compound of the pyrimidine family, often called a base, consisting of a ring containing both nitrogen and carbon atoms, and a methyl group. It occurs in combined form in many important biological molecules, particularly DNA (where its complementary base is adenine). It or its corresponding nucleoside or nucleotide may be prepared from DNA by selective techniques of hydrolysis
A base, C{5}H{6}N{2}O{2}, obtained by applying sulphuric acid to thymic acid; it pairs with adenine in DNA
