| polymorphic genetic markers | Inherited characteristics that occur within a given population as two or more traits. (05 Mar 2000) |
|---|---|
| skin diseases, genetic | Diseases of the skin with a genetic component, usually the result of various inborn errors of metabolism. (12 Dec 1998) |
| suppression, genetic | The restoration of the wild-type phenotype in an organism possessing a mutationally altered genotype. The effects of the mutation may be suppressed by a second "suppressor" mutation on a different gene, by a suppressor mutation on the same gene but located at a distance from the site of the primary mutation, or by the presence of a cytoplasmic suppressor due to a change in non-chromosomal DNA. (12 Dec 1998) |
| transcription, genetic | The transfer of genetic information from DNA to messenger RNA by DNA-directed RNA polymerase. It includes reverse transcription and transcription of early and late genes expressed early in an organism's life cycle or during later development. (12 Dec 1998) |
| transduction, genetic | Transfer of bacterial DNA by phages from the infected bacterium in which the DNA originates to another bacterium. (12 Dec 1998) |
| transformation, genetic | The unidirectional transfer and incorporation of foreign DNA by prokaryotic or eukaryotic cells and the subsequent recombination of part or all of that DNA into the cell's genome. (glossary of genetics: classical and molecular, 5th ed) (12 Dec 1998) |
| translation, genetic | Formation of peptides on ribosomes, directed by messenger RNA. (12 Dec 1998) |
| epistasis, genetic | A form of gene interaction whereby one gene interferes with the phenotypic expression of another nonallelic gene or genes. Genes whose expression is altered by nonallelic genes are said to be "hypostatic" or to exhibit "hypostasis". (12 Dec 1998) |
