| MDS+ | minimum data set (plus) |
| NMDS | nursing minimum data set |
| amidation site | <molecular biology> A C terminus consensus sequence, required for C terminus amidation of peptides. Consensus is glycine, followed by 2 basic amino acids (arg or lys). (18 Nov 1997) |
|---|---|
| antibody combining site | <immunology> In immune network theory, an idiotope, an antigenic site of an antibody that is responsible for that antibody binding to an antigenic determinant (epitope). Also used of the site on a ligand molecule to which a cell surface receptor binds. (18 Nov 1997) |
| antigen-binding site | <immunology> In immune network theory, an idiotope, an antigenic site of an antibody that is responsible for that antibody binding to an antigenic determinant (epitope). Also used of the site on a ligand molecule to which a cell surface receptor binds. (18 Nov 1997) |
| antigen-combining site | See: paratope. (05 Mar 2000) |
| apurinic site | <molecular biology> Sites in DNA from which purines have been lost by cleavage of the deoxy ribose N glycosidic linkage. (18 Nov 1997) |
| apyrimidinic site | <molecular biology> A site on DNA where a base is missing, in this case a pyrimidine (either cytosine or thymine), but the phosphodiester backbone is still intact. Compare: apurinic site. (09 Oct 1997) |
| ATT site | <molecular biology> A site on the chromosome of the bacteria E. Coli where the lambda bacteriophage can insert its genome (all of its DNA) so that it can lie dormant and have its DNA reproduced whenever the bacterium reproduces for as long as the bacterium remains healthy (that is, so that it becomes lysogenic). (09 Oct 1997) |
| gaylus-site | <chemical> A yellowish white, translucent mineral, consisting of the carbonates of lime and soda, with water. Origin: Named after Gay-Lussac, the French chemist. (20 Mar 1998) |
| receptor site | Point of attachment of viruses, hormones, or other activators to cell membranes. (05 Mar 2000) |
| catalytic site | <chemistry> The site on an enzyme where the substrate or substrates (the reactants of a chemical or biochemical reaction) attach in order to convert to the product or products of the reaction, at a much higher speed than the substrate would need to convert to the product alone. (16 Mar 1998) |
| replication site | The in vivo site on DNA of DNA replication. (05 Mar 2000) |
| restriction enzyme cutting site | <molecular biology> A specific nucleotide sequence of DNA at which a particular restriction enzyme cuts the DNA. Some sites occur frequently in DNA (for example, every several hundred basepairs), others much less frequently (rare-cutter, for example, every 10,000 base pairs). (10 Mar 1998) |
| restriction site | A sequence in DNA that can be recognised and cut by a specific restriction enzyme. (12 Dec 1998) |
| restriction-site polymorphism | DNA polymorphism in which the sequence of one form of the polymorphism contains a recognition site for a particular endonuclease, but the sequence of the other form lacks such a site. (05 Mar 2000) |
| chi site | <molecular biology> Short, active sequences of DNA which strongly encourages crossing over of chromosomes to occur at that site. These sites become chiasmata more often than other sites. (05 Jan 1998) |
