| 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) |
| ambisense expression strategy | <molecular biology> The coding of viral proteins in both the sense (coding) and antisense (noncoding) strands of complementary mRNA, so that the viral proteins are produced no matter which strand gets translated. (09 Oct 1997) |
| gene expression | <molecular biology> The full use of the information in a gene via transcription and translation leading to production of a protein and hence the appearance of the phenotype determined by that gene. Gene expression is assumed to be controlled at various points in the sequence leading to protein synthesis and this control is thought to be the major determinant of cellular differentiation in eukaryotes. (18 Nov 1997) |
| gene expression regulation | Any of the processes by which nuclear, cytoplasmic, or intercellular factors influence the differential control of gene action at the level of transcription or translation. These processes include gene activation and genetic induction. (12 Dec 1998) |
| gene expression regulation, archaeal | Any of the processes by which cytoplasmic or intercellular factors influence the differential control of gene action in archaea. (12 Dec 1998) |
| gene expression regulation, bacterial | Any of the processes by which cytoplasmic or intercellular factors influence the differential control of gene action in bacteria. (12 Dec 1998) |
| gene expression regulation, developmental | Any of the processes by which nuclear, cytoplasmic, or intercellular factors influence the differential control of gene action during the developmental stages of an organism. (12 Dec 1998) |
| gene expression regulation, enzymologic | Any of the processes by which nuclear, cytoplasmic, or intercellular factors influence the differential control of gene action in enzyme synthesis. (12 Dec 1998) |
| gene expression regulation, fungal | Any of the processes by which nuclear, cytoplasmic, or intercellular factors influence the differential control of gene action in fungi. (12 Dec 1998) |
| gene expression regulation, leukaemic | Any of the processes by which nuclear, cytoplasmic, or intercellular factors influence the differential control of gene action in leukaemia. (12 Dec 1998) |
| gene expression regulation, neoplastic | Any of the processes by which nuclear, cytoplasmic, or intercellular factors influence the differential control of gene action in neoplastic tissue. (12 Dec 1998) |
