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.
Thiamine, also known as thiamin and vitamin B1, is a vitamin, an essential micronutrient for humans and animals. [3][4] It is found in food and commercially synthesized to be a dietary supplement or medication. [1][5] Phosphorylated forms of thiamine are required for some metabolic reactions, including the breakdown of glucose and amino acids. [1]
Thymine, or 5-methyluracil, is a pyrimidine base found in the nucleic acid DNA. In RNA thymine is swapped for uracil to represent the same genetic information. In DNA, thymine (T) connects to adenine (A) by two hydrogen bonds .
Five nucleobases— adenine (A), cytosine (C), guanine (G), thymine (T), and uracil (U)—are called primary or canonical. They function as the fundamental units of the genetic code, with the bases A, G, C, and T being found in DNA while A, G, C, and U are found in RNA.
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 (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.
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.
Formation of thymine dimer lesion in DNA. The photon causes two consecutive bases on one strand to bind together, destroying the normal base-pairing double-strand structure in that area.. Pyrimidine dimers represent molecular lesions originating from thymine or cytosine bases within DNA, resulting from photochemical reactions. [1] [2] These lesions, commonly linked to direct DNA damage, [3 ...
thymine (countable and uncountable, plural thymines) (organic chemistry, genetics) A heterocyclic base, 5-methyl pyrimidine-2,4(1H,3H)-dione; it pairs with adenine in DNA. Coordinate terms: adenine, cytosine, guanine
Thymidine (symbol dT or dThd), also known as deoxythymidine, deoxyribosylthymine, or thymine deoxyriboside, is a pyrimidine deoxynucleoside. Deoxythymidine is the DNA nucleoside T, which pairs with deoxyadenosine (A) in double-stranded DNA.
