Thymine (/ ˈθaɪmɪn /) (symbol T or Thy) is one of the four nucleotide bases in the nucleic acid of DNA that are represented by the letters G–C–A–T. The others are adenine, guanine, and cytosine. Thymine is also known as 5-methyluracil, a pyrimidine nucleobase. In RNA, thymine is replaced by the nucleobase uracil.
Thymine is one of the four nitrogenous nucleobases that form the basic building blocks of deoxyribonucleic acid (DNA). Also known as 5-methyluracil, thymine (T) is a pyrimidine nucleobase, which pairs with adenine (A), a purine nucleobase.
Thymine is a pyrimidine nucleobase that is uracil in which the hydrogen at position 5 is replaced by a methyl group. It has a role as a human metabolite, an Escherichia coli metabolite and a mouse metabolite.
thymine, organic compound of the pyrimidine family that is a constituent of deoxyribonucleic acid (DNA). DNA, along with RNA (ribonucleic acid), regulates hereditary characteristics in all living cells.
Thymine is a pyrimidine nucleobase with a chemical formula of C5H6N2O2. A pyrimidine is a heterocyclic aromatic organic compound with a single ring (called a pyrimidine ring) with alternating carbon and nitrogen atoms. The chemical structure of thymine involves both aromatic and ketone functional groups.
Thymine is one of the five bases used to build nucleic acids. It is also known as 5-methyluracil or by the abbreviations T or Thy. Thymine is found in DNA, where it pairs with adenine via two hydrogen bonds. In RNA, thymine is replaced by uracil.
Thymine (T) is one of the four nucleotide bases in DNA, with the other three being adenine (A), cytosine (C) and guanine (G). Within a double-stranded DNA molecule, thymine bases on one strand pair with adenine bases on the opposite strand.
The structure of RNA (Figure 2.137) is very similar to that of a single strand of DNA. Built of ribonucleotides, joined together by the same sort of phosphodiester bonds as in DNA, RNA uses uracil in place of thymine.
Thymine (T) is a key nucleobase in DNA, forming base pairs with adenine and contributing to the genetic code. Learn about its structure, properties, and biological significance.
