| 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) |
| structuralism | A branch of psychology interested in the basic structure and elements of consciousness. (05 Mar 2000) |
| genes, structural | Genes that code for proteins required for the enzymatic and structural functions of cells. They include developmental and differentiated genes. (12 Dec 1998) |
|---|---|
| genes, structural, bacterial | DNA sequences that code for RNA and for the proteins required for the enzymatic and structural function of bacterial cells. (12 Dec 1998) |
| genes, structural, fungal | DNA sequences that code for RNA and for the proteins required for the enzymatic and structural function of fungal cells. (12 Dec 1998) |
| genes, structural, helminth | DNA sequences that code for RNA and for the proteins required for the enzymatic and structural function of helminthic cells. (12 Dec 1998) |
| genes, structural, insect | DNA sequences that code for RNA and for proteins required for the enzymatic and structural function of insect cells. (12 Dec 1998) |
| genes, structural, neoplasm | DNA sequences that code for RNA and for the proteins required for the enzymatic and structural function of neoplastic cells. (12 Dec 1998) |
| genes, structural, plant | DNA sequences that code for RNA and for the proteins required for the enzymatic and structural function of plant cells. (12 Dec 1998) |
| genes, structural, protozoan | DNA sequences that code for RNA and for the proteins required for the enzymatic and structural function of protozoan cells. (12 Dec 1998) |
| genes, structural, viral | DNA or RNA sequences that code for RNA and for the proteins required for the enzymatic and structural function of viral cells. (12 Dec 1998) |
| viral structural proteins | Viral proteins that do not regulate transcription. 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) |
