They are coded by viral structural genes and include nucleocapsid core proteins (gag proteins), enzymes (pol proteins), and membrane components (env proteins). Transcription of viral structural genes is regulated by viral regulatory proteins. (12 Dec 1998) |
|---|---|
| models, structural | A representation, generally smale in scale, to show the structure, construction, or appearance of something. (12 Dec 1998) |
| structural | <anatomy> Pertaining to or affecting the structure. (18 Nov 1997) |
| structural biology | <study> The study of the three dimensional structures of biological molecules (such as proteins) and their mutual interactions as a means of understanding the functions of these molecules within the cell. (09 Oct 1997) |
| structural colour | A colour created by an optical effect (e.g., via interference, refraction, or diffraction). Many naturally occurring blues fall in this class. Compare: natural pigment. Synonym: schemochromes. (05 Mar 2000) |
| structural formula | A formula in which the connections of the atoms and groups of atoms, as well as their kind and number, are indicated. Synonym: constitutional formula, graphic formula. (05 Mar 2000) |
| structural gene | A gene that codes for a product (e.g. An enzyme, structural protein, tRNA), as opposed to a gene that serves a regulatory role. (18 Nov 1997) |
| structural interface | In dentistry, a boundary between tooth and restorative material. (05 Mar 2000) |
| structural isomerism | Isomerism involving the same atoms in different arrangements; e.g., butyric acids, leucine and isoleucine, glucose and fructose. (05 Mar 2000) |
| structural isomers | <chemistry> Are organic compounds that have the same som formula, meaning the same number of carbons, hydrogens or other type ot atoms. They differ from each other in the way the atoms are connected. Examples are n-butane and 2-methylpropane or ethanol and dimethylether. (09 Jan 1998) |
| breast cancer susceptibility genes | Inherited factors that predispose to breast cancer. Put otherwise, these genes make one more susceptible to the disease and so increase the risk of developing breast cancer. Two of these genes, BRCA1 and BRCA2, have been identified (and prominently publicised). Several other genes (those for the Li-Fraumeni syndrome, Cowden disease, Muir-Torre syndrome, and ataxia-telangiectasia) are also known to predispose to breast cancer. However, since all of these known breast cancer susceptibility genes together do not account for more than a minor fraction (1/5th at most) of breast cancer that clusters in families, it is clear that more breast cancer genes remain to be discovered. (12 Dec 1998) |

| genes | Located in the nucleus of the cell, genes contain hereditary information that is transferred from cell to cell. (09 Oct 1997) |
| genes, abl | Retrovirus-associated DNA sequences (abl) originally isolated from the abelson murine leukaemia virus (ab-mulv). The proto-oncogene abl (c-abl) codes for a protein that is a member of the tyrosine kinase family. The human c-abl gene is located at 9q34.1 on the long arm of chromosome 9. It is activated by translocation to bcr on chromosome 22 in chronic myelogenous leukaemia. (12 Dec 1998) |
| genes, apc | Tumour suppressor genes located in the 5q21 region on the long arm of chromosome 5. The mutation of these genes is associated with familial adenomatous polyposis (apc stands for adenomatous polyposis coli) and gardner's syndrome, as well as some sporadic colourectal cancers.
