| radiation inactivation | The technique of inactivating proteins in freeze dried (lyophilised) preparations using high energy particles (e.g. Electrons). One high energy particle can apparently inactivate all of the components of a multisubunit polypeptide, the method is therefore used to determine the molecular weight of functional oligomers. (18 Nov 1997) |

| X inactivation | <cell biology> The inactivation of one or other of each pair of X chromosomes to form the Barr body in female mammalian somatic cells. Thus tissues whose original zygote carried heterozygous X borne genes should have individual cells expressing one or other but not both of the X borne gene products. The inactivation is thought to occur early in development and leads to mosaicism of expression of such genes in the body. See: Lyon hypothesis. (18 Nov 1997) |
| inactivation | <neurology, physiology> For example of voltage gated sodium channels: process by which sodium channels that have been activated or opened by depolarisation subsequently close during the depolarisation. Distinguished from activation by its slower kinetics. (18 Nov 1997) |
| insertional inactivation | The inactivation of a gene due to the insertion of exogenous genetic material into that gene. (14 Nov 1997) |
| enzyme inactivation | The disappearance of an enzyme's activity during in vitro conditions, such as during a lab preparation of the enzyme, where the enzyme is exposed to conditions not normally found within its environment inside a living cell (like different pH, excess or too little salt, temperature changes, etc.) (09 Oct 1997) |
| acceptor RNA | rNA |
| antisense RNA | <molecular biology> A complementary RNA sequence that binds to (and thus blocks the transcription of) a naturally-occuring (sense) messenger RNA molecule. These proteins can be used to selectively turn off production of certain proteins or block viral genetic instructions, by marking them for destruction by cellular enzymes, in order to prevent the building of new virus or the infection of new cells.

| p68 RNA helicase | <enzyme> An RNA helicase isolated from uv-induced tumours in mice; amino acid sequence has been determined Registry number: EC 2.7.7.- Synonym: dead box helicase p68 (26 Jun 1999) |
| masked messenger RNA | <molecular biology> Long lived and stable mRNA found originally in the oocytes of echinoderms and constituting a store of maternal information for protein synthesis that is unmasked (derepressed) during the early stages of morphogenesis. In these early stages the rate of cell division is so rapid that transcription from the embryonic genome cannot occur. Undoubtedly not restricted to oocytes and the term can be applied to any mRNA which is present in inactive form. (18 Nov 1997) |
| ribosomal RNA | <molecular biology> A nucleic acid found in all living cells. Plays a role in transferring information from DNA to the protein-forming system of the cell. (16 Dec 1997) |
| messenger-like RNA | An ill-defined form of RNA, of high molecular weight, that never leaves the nucleus and is thought to be the precursor of messenger RNA. (05 Mar 2000) |
| messenger RNA | <molecular biology> Single stranded RNA molecule that specifies the amino acid sequence of one or more polypeptide chains. This information is translated during protein synthesis when ribosomes bind to the mRNA. In prokaryotes, mRNA is normally formed by splicing a large primary transcript from a DNA sequence and protein synthesis starts while the mRNA is still being synthesised. Prokaryote mRNAs are usually very short lived (average t 1/2 is 5mins.). In contrast, in eukaryotes the primary transcripts (HnRNA) are synthesised in the nucleus and they are extensively processed to give the mRNA that is exported to the cytoplasm where protein synthesis takes place. This processing includes the addition of a 5' 5' linked 7 methyl guanylate cap at the 5' end and a sequence of adenylate groups at the 3' end, the poly A tail, as well as the removal of any introns and the splicing together of exons, only 10% of HnRNA leaves the nucleus. Eukaryote mRNAs are comparatively long lived with a half life ranging from 30minutes to 24 hours. (27 Jun 1999) |
