Thymine (T) is one of four chemical bases in DNA , the other three being adenine (A), cytosine (C), and guanine (G). Within the DNA molecule, thymine bases located on one strand form chemical bonds with adenine bases on the opposite strand.
What is thymine classified?
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. It is a pyrimidine nucleobase and a pyrimidone. One of four constituent bases of DNA.
What is thymine in biology?
Thymine is one of the pyrimidine bases found in the nucleic acid of deoxyribonucleic acid (DNA), along with adenine, guanine, and cytosine (A, G, and C, respectively). These bases are the building blocks of DNA and all life forms on earth.
Is thymine a compound?
Thymine, organic compound of the pyrimidine family that is a constituent of deoxyribonucleic acid (DNA). It is also part of thymidylic acid, a nucleotide (a larger structural unit composed of a nucleoside and phosphoric acid), which is a phosphate ester of thymidine. ...
Why is thymine a pyrimidine?
Purines and pyrimidines are the nitrogen bases that hold DNA strands together through hydrogen bonds. ... The pyrimidines in DNA are cytosine and thymine; in RNA, they are cytosine and uracil. Purines are larger than pyrimidines because they have a two-ring structure while pyrimidines only have a single ring.
What is the main function of thymine?
In DNA, thymine (T) binds to adenine (A) via two hydrogen bonds, thereby stabilizing the nucleic acid structures . Thymine combined with deoxyribose creates the nucleoside deoxythymidine, which is synonymous with the term thymidine.
Is uracil a DNA?
Uracil is a nucleotide , much like adenine, guanine, thymine, and cytosine, which are the building blocks of DNA, except uracil replaces thymine in RNA. So uracil is the nucleotide that is found almost exclusively in RNA.
What is another name for thymine?

What is thymine made up of?
Thymine is a pyrimidine nucleobase with a chemical formula of C 5 H 6 N 2 O 2 . Pyrimidine is a heterocyclic aromatic organic compound with a single ring (called a pyrimidine ring) with alternating carbon and nitrogen atoms.
Why is thymine present in DNA?
In DNA, deamination of CYTOSINE (conversion of CYTOSINE to URACIL) take place spontaneously . ... So this is the reason why DNA contain THYMINE instead of URACIL. Moreover, URACIL has more base pair affinity to ADENINE, but it can also pair up with other bases including itself.
What does cytosine stand for?
Reviewed on 6/3/2021. C (cytosine): C stands for cytosine , a DNA nucleotide that which is one member of the base pair in DNA consisting of guanine and cytosine. This base pair is conventionally abbreviated G-C (or GC). The other base pair in DNA is adenine and thymine which is conventionally abbreviated A-T (or AT).
Is thymine present in DNA?
Thymine (T) is one of four chemical bases in DNA , the other three being adenine (A), cytosine (C), and guanine (G). Within the DNA molecule, thymine bases located on one strand form chemical bonds with adenine bases on the opposite strand.
Is cytosine part of DNA?
DNA is made up of four building blocks called nucleotides: adenine (A), thymine (T), guanine (G), and cytosine (C).
Is thymine a phosphate?
Phosphate Backbone
Attached to each sugar is one of four bases–adenine (A), cytosine (C), guanine (G), or thymine (T).
Is a pyrimidine?
Adenine (A) and guanine (G) are purines, and cytosine (C), thymine (T), and uracil (U) are pyrimidines. These are the most important parts in the nucleic acid, and genetic information is stored in the sequence of these molecules.
