KnowraThymineThymineThymine is a pyrimidine nucleobase in DNA that pairs with adenine. RNA generally uses uracil instead.BriefConnectNucleobase: A nitrogen-containing molecule that forms the information-bearing bases of nucleic acids. Thymine belongs to this chemical family.Watson–Crick base pairing: The specific hydrogen-bonding pattern that pairs complementary bases in DNA. It describes thymine’s pairing with adenine.Uracil: A pyrimidine nucleobase used in RNA in place of thymine. RNA usually uses uracil where DNA uses thymine.Transition mutation: A point mutation that replaces a purine with another purine or a pyrimidine with another pyrimidine. Thymine-to-cytosine changes are pyrimidine transitions.Pyrimidine: A nitrogen-containing heterocyclic compound with a six-membered ring. Thymine is built on a pyrimidine ring.DNA replication: The process by which a cell copies its DNA before cell division. Adenine in the template directs incorporation of thymine into a new strand.Cytosine: A pyrimidine nucleobase that pairs with guanine in DNA and RNA. It is another DNA pyrimidine, but pairs with a different base.Ultraviolet radiation: Electromagnetic radiation with wavelengths shorter than visible light. Ultraviolet exposure can link adjacent thymines and damage DNA.DNA: A nucleic acid that stores hereditary information in most organisms. Thymine is one of DNA’s four standard bases.DNA repair: Cellular processes that detect and correct damage or errors in DNA. Repair systems recognize thymine-related lesions and mismatches.Show all 20Linked from 8 pagesPyrimidineBroader topic: Thymine distinguishes DNA’s standard bases from those used in RNA.ThymidineRelated: Thymine is the base attached to deoxyribose in thymidine.GuanineCompared with: Thymine illustrates the contrasting DNA pair rather than guanine's cytosine pair.Albrecht KosselBroader topic: Kossel helped identify thymine among the bases obtained from nucleic acids.Show all 8
