| thymine dimer | <molecular biology> Dimer that can be formed in DNA by covalent linkage between two adjacent (cis) thymidine residues, in response to ultraviolet irradiation. Occurrence potentially mutagenic, although repair enzymes exist that can excise thymine dimers. See: xeroderma pigmentosum. (18 Nov 1997) |
|---|
| pyrimidine dimer | <biochemistry> A dimer product found in DNA chains damaged by ultraviolet irradiation. Most frequently thymidine dimers. They consist of two adjacent pyrimidine nucleotides, usually thymine nucleotides, in which the pyrimidine residues are covalently joined by a cyclobutane ring. These dimers stop DNA replication.

| d-dimer test | Test that detects the cross-linked fibrin degradation fragment, D-dimer. Elevations in this fragment are seen in primary and secondary fibrinolysis, during thrombolytic or defibrination therapy with tissue plasminogen activator, as a result of thrombotic disease, such as deep-vein thrombosis, pulmonary embolism or DIC, in vasoocclusive crisis of sickle cell anaemia, in malignancies, and in surgery. (05 Mar 2000) |
| dimer | A molecule which consists of two similar (but not necessarily identical) subunits. The term could also be used as a verb referring to the act of the two subunits coming together (to dimerize). (09 Oct 1997) |
| hypoxanthine-aminopterin-thymine medium | A type of agar growth medium (a selective medium) which is used to select for cells that are able to make their nucleic acids out of hypoxanthine and/or thymine. All cells are prevented from making nucleotides by any other means (due to the presence of aminopterin or other drugs in the medium), so cells which are unable to use hypoxanthine and/or thymine to do this will not grow, multiply, and become visible colonies. This leaves the cells which are being selected for. (09 Oct 1997) |
| thymine | <biochemistry> Pyrimidine base found in DNA (in place of uracil of RNA). (18 Nov 1997) |
| thymine, 2-oxoglutarate dioxygenase | <enzyme> 5-hydroxymethyluracil,2-oxoglutarate dioxygenase was formerly EC 1.14.11.5; for this activity, substrate thymine may be replaced by uracil/analogs Chemical name: 5-hydroxymethyluracil,2-oxoglutarate dioxygenase /od/ thymine 7-hydroxylase Registry number: EC 1.14.11.6 Synonym: thymine 7-hydroxylase, alpha-ketoglutarate dioxygenase, thymine (26 Jun 1999) |
| thymine deoxyribonucleoside | <biochemistry> Term that is always used in practice for the nucleoside thymine deoxyriboside, not the riboside which naming of the other nucleosides might lead one to expect. (18 Nov 1997) |
| thymine deoxyribonucleotide | A component of DNA; originally and properly called thymidylic acid, but use of deoxy-is less ambiguous, as ribothymidylic acid is now known to exist. Synonym: thymine deoxyribonucleotide. (05 Mar 2000) |
| thymine nucleotide | A major constituent of DNA. Synonym: thymidine 5'-monophosphate, thymine nucleotide. (05 Mar 2000) |
| thymine nucleotides | Phosphate esters of thymidine in n-glycosidic linkage with ribose or deoxyribose, as occurs in nucleic acids. (12 Dec 1998) |
| thymine dimer |
A pair of abnormally chemically bonded adjacent thymine bases in DNA, resulting from damage by ultra-violet irradiation. The cellular processes that repair this lesion often make errors that create mutations.
