| secretion vector | <molecular biology> A DNA vector in which the protein product is both expressed and secreted (excreted) from the cell. (09 Oct 1997) |
|---|---|
| host-vector system | A combination of a bacterial host cell (i.e. A specific strain) and a virus vector (i.e. A particular bacteriophage strain) which work well together for DNA cloning. (09 Oct 1997) |
| shuttle vector | <molecular biology> Cloning vector that replicate in cells of more than one organism, for example E. Coli and yeast. This combination allows DNA from yeast to be grown in E. Coli and tested directly for complementation in yeast. Shuttle vectors are constructed so that they have the origins of replication of the various hosts. (18 Nov 1997) |
| spatial vector | A cardiac vector represented in more than one plane simultaneously; two-or three-dimensional orientation of a vector. (05 Mar 2000) |
| instantaneous vector | The resultant vector of the heart's action currents at any given moment, usually represented as an arrow of appropriate direction and magnitude. (05 Mar 2000) |
| expression vector | <molecular biology> A cloning vector that contains the necessary regulatory sequences to allow transcription and translation of a cloned gene or genes and thus transcribe and clone DNA. (13 Nov 1997) |
| axial | <anatomy> Position as it relates to the CNS. Intra-axial is within the CNS, extra-axial is outside the CNS. (16 Dec 1997) |
| axial ametropia | That resulting from a shortening or lengthening of the eyeball on the optic axis, causing hyperopia or myopia, respectively. (05 Mar 2000) |
| axial aneurysm | An aneurysm involving the entire circumference of a blood vessel. (05 Mar 2000) |
| axial angle | An angle formed by two surfaces of a body, the line of union of which is parallel with its axis; the axial angle's of a tooth are the distobuccal, distolabial, distolingual, mesiobuccal, mesiolabial, and mesiolingual. (05 Mar 2000) |
| axial cataract | A lenticular opacity in the visual axis of the lens. (05 Mar 2000) |
| axial current | The central rapidly moving portion of the bloodstream in an artery. (05 Mar 2000) |
| axial filament | The central filament of a flagellum or cilium; with the electron microscope it is seen as a complex of nine peripheral diplomicrotubules and a central pair of microtubules. Synonym: axoneme. (05 Mar 2000) |
| axial hyperopia | Hyperopia due to shortening of the anteroposterior diameter of the globe of the eye. (05 Mar 2000) |
| axial muscle | <anatomy> One of the skeletal muscle's of the trunk or head. (05 Mar 2000) |
