| foldback DNA | <molecular biology> Sections of single-stranded DNA which have sequences that are palindromes, or which read the same both backwards and forwards, that may base pair with each other instead of with the right sections of the other strand during renaturation into double-stranded DNA. (09 Oct 1997) |
|---|---|
| 5-methylcytosine-DNA glycosylase | <enzyme> Binds equally well to methylated and non-methylated DNA; isolated from developing chicken embryos and mouse fibroblasts; mw 52.5 kD Registry number: EC 3.2.2.- (26 Jun 1999) |
| 8-hydroxy-5-deazaflavin-dependent DNA photolyase | <enzyme> From anacystis nidulans; purified in streptomyces coelicolor; distinguish from folate-dependent DNA photolyase Registry number: EC 4.1.99.- Synonym: 8-hdfd-DNA photolyase (26 Jun 1999) |
| formamidopyridine-DNA glycosylase | <enzyme> Substrate is the ring-opened form of 7-methylguanine; has been sequenced; genbank af026691 Registry number: EC 3.2.2.23 Synonym: fap-DNA glycosylase, fapy-DNA glycosylase, formamidopyrimidine-DNA glycosylase, 8-oxoguanine DNA glycosylase, 8-hydroxyguanine DNA glycosylase, 8-hydroxyguanine endonuclease, 8-oh-gua endonuclease, fpg protein, E coli, fpg gene product, E coli, mutm protein, oh8 guanine excision repair enzyme, ogg1 gene product (26 Jun 1999) |
| forms of DNA i, II and III | Refers to circular DNA removed from viruses and as plasmids. Form I is the DNA in its normal, supercoiled form. Form II is the DNA after one of the two strands has been nicked (cut apart), and is circular. Form III is the DNA after both strands have been broken, and is linear. (09 Oct 1997) |
| linker DNA | The DNA found between nucleosomes on chromatin; since it is not complexed to proteins as strongly as other forms of DNA, it is accessible to exonuclease hydrolysis. (05 Mar 2000) |
| abelson leukaemia virus | A defective murine leukaemia virus capable of transforming lymphoid cells and producing a rapidly progressing lymphoid leukaemia after superinfection with friend, moloney, or rauscher virus. (12 Dec 1998) |
| Abelson murine leukaemia virus | A retrovirus belonging to the Type C retrovirus group subfamily (family Oncovirinae) which is associated with leukaemia and produces in vitro transformation of mouse cells. (05 Mar 2000) |
| adeno-associated virus | <virology> A genus of viruses in the family Parvoviridae which are all defective viruses (unable to replicate by themselves) and depend on the co-infection of their host cell by other, nondefective viruses to help them replicate. (09 Oct 1997) |
| adenoidal-pharyngeal-conjunctival virus | <virology> An icosahedral (20-sided) virus that contains DNA, there are over 40 different adenovirus varieties, some of which cause the common cold. (10 May 1997) |
| adenosatellite virus | <virology> A genus of viruses in the family Parvoviridae which are all defective viruses (unable to replicate by themselves) and depend on the co-infection of their host cell by other, nondefective viruses to help them replicate. (09 Oct 1997) |
| african horse sickness virus | A species of orbivirus that causes disease in horses, mules, and donkeys. (12 Dec 1998) |
| african swine fever virus | The lone species of the genus african swine fever-like viruses. The virus causes a fatal disease among domestic pigs in africa and a less virulent infection in europe. The virus is present in soft ticks (ornithodoros moubata), warthogs, or domestic pigs. Originally listed as a species of iridoviridae, the virus exhibits some similarities to poxviridae but its differences warranted placement in a separate genus of an, as yet unknown, family. (12 Dec 1998) |
| AIDS-related virus | An obsolete term for human immunodeficiency virus. (05 Mar 2000) |
| Akabane virus | A virus of the genus Bunyavirus, family Bunyaviridae, causing abortion in cattle and congenital arthrogryposis and hydranencephaly in bovine foetuses in Israel, Japan, and Australia; it is transmitted by mosquitoes. (05 Mar 2000) |
