| expression | <molecular biology> The process by which a gene's coded information is converted into the structures present and operating in the cell. Expressed genes include those that are transcribed into mRNA and then translated into protein and those that are transcribed into RNA but not translated into protein (for example, transfer and ribosomal RNAs). (06 Aug 1998) |
|---|---|
| expression cloning | <molecular biology> A vector that results in the expression of inserted DNA sequences when propagated in a suitable host cell, i.e. The protein coded for by the DNA is synthesised by the host's system. (06 Aug 1998) |
| expression library | <molecular biology> A library of DNA fragments which was created with an expression vector so that any genes present in the library are expressed. (09 Oct 1997) |
| expression site | The location in the genome of the gene for the variable surface glycoprotein that is currently being expressed (an expression-linked copy) by the trypanosome (a parasitic protozoan which causes the disease African sleeping sickness). most of these sites are near the ends, or telomeres, of a chromosome. (09 Oct 1997) |
| expression system | <molecular biology> Combination of an expression vector, its cloned DNA, and the host for the vector that provide a context to allow foreign gene function in a host cell, that is, produce proteins at a high level. (13 Nov 1997) |
| 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) |
| expression, gene | A gene speaks. When a gene is expressed, the information encoded in the gene is translated into protein or RNA structures present and operating in the cell. Expressed genes include genes that are transcribed into messenger RNA (mRNA) and then translated into protein as well as those genes that are transcribed into RNA (such transfer and ribosomal RNAs) but not translated into protein. (12 Dec 1998) |
| expression-linked copy | <molecular biology> One of many different versions of the variable surface glycoprotein gene of the trypanosome (a parasitic protozoan which causes the disease African sleeping sickness), refers to whichever one of them is currently being expressed on the outer surface of the trypanosome. (09 Oct 1997) |
| 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) |
|---|---|
| mammalian expression vector | <molecular biology> A vector that will produce large amounts of eukaryotic protein taxonomy notwithstanding, and not necessarily a protein from a mammal. (20 Mar 1998) |
| 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) |
| gene expression regulation, plant | Any of the processes by which nuclear, cytoplasmic, or intercellular factors influence the differential control of gene action in plants. (12 Dec 1998) |
| gene expression regulation, viral | Any of the processes by which cytoplasmic factors influence the differential control of gene action in viruses. (12 Dec 1998) |
| muscles of facial expression | The numerous muscles supplied by the facial nerve that are attached to and move the skin of the face. Nomina Anatomica also includes the buccinator muscle in this group; even though it functions primarily in mastication. Synonym: musculi faciales, facial muscles, mimetic muscles. (05 Mar 2000) |
| differential gene expression | Gene expression that responds to signals or triggers; a means of gene regulation; e.g., effects of certain hormones on protein biosynthesis. (05 Mar 2000) |
| expression |
the feelings expressed on a person's face; "a sad expression"; "a look of triumph"; "an angry face" expression without words; "tears are an expression of grief"; "the pulse is a reflection of the heart's condition" the communication (in speech or writing) of your beliefs or opinions; "expressions of good will"; "he helped me find verbal expression for my ideas"; "the idea was immediate but the verbalism took hours" saying: a word or phrase that particular people use in particular situations; "pardon the expression" formulation: the style of expressing yourself; "he suggested a better formulation"; "his manner of expression showed how much he cared" formula: a group of symbols that make a mathematical statement (genetics) the process of expressing a gene construction: a group of words that form a constituent of a sentence and are considered as a single unit; "I concluded from his awkward constructions that he was a foreigner" the act of forcing something out by squeezing or pressing; "the expression of milk from her breast"

| expression vector |
A cloning vector that has been constructed in such a way that, after insertion of a DNA molecule, its coding sequence is properly transcribed and the RNA is translated. The cloned gene is put under the control of a promoter sequence for the initiation of transcription, and often also has a transcription termination sequence at its end. Such promoters are termed high level; examples include P1 (the leftward promoter of phage l) and the promoter of the yeast PGK (phosphoglycerate kinase) gene.
