| 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) |
| integrated rate expression | An equation of a chemical or enzyme-catalyzed reaction for the entire progress curve. (05 Mar 2000) |
| oocyte expression | <molecular biology> Technique whereby the cellular machinery of an oocyte (typically that of Xenopus) is utilised to transcribe functional protein from microinjected RNA. (18 Nov 1997) |
| 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, 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 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-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) |
| 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) |
| facial expression | Observable changes of expression in the face in response to emotional stimuli. (12 Dec 1998) |
