| synchronous cell population | <cell culture> A culture of cells that all divide in synchrony. Particularly useful for certain studies of the cell cycle, cells can be made synchronous by depriving them of essential molecules, which are then restored. Synchronisation breaks down after a few cycles, however, as individual cells have unique division rates. (19 Jan 1998) |
|---|---|
| q in population genetics | The frequency of the less common of two different alternative (allelic) versions of a gene. (the frequency of the more common allele is p). (12 Dec 1998) |
| topotypical population | <zoology> Population occurring at the type locality from which the type specimen was taken. (09 Jan 1998) |
| urban population | The inhabitants of a city or town, including metropolitan areas and suburban areas. (12 Dec 1998) |
| genetic | <biology> Pertaining to reproduction or to birth or origin. (07 May 1998) |
| genetic amplification | A process for producing an increase in pertinent genetic material, particularly for increasing the proportion of plasmid DNA to that of bacterial DNA. Includes the production of extrachromosomal copies of the genes for RNA. (05 Mar 2000) |
| genetic assimilation | <genetics> A situation in which a characteristic that is normally expressed only in certain environmental situations becomes fixed in a population so that it no longer requires environmental factors to be expressed. (07 May 1998) |
| genetic association | The occurrence together in a population, more often than can be readily explained by chance, of two or more traits of which at least one is known to be genetic. (05 Mar 2000) |
| genetic block | <biochemistry, molecular biology> An obstruction in a biochemical pathway caused by a mutation that has crippled production of an enzyme critical to the pathway. (07 May 1998) |
| genetic burden | The genetic debt due to harmful mutation but as yet undischarged. (In a large population of fixed size every mutation with diminished genetic fitness will eventually become extinct and depending on the details of inheritance and phenotype must be paid for by a fixed number of genetic deaths per mutation, the genetic debt.) (05 Mar 2000) |
| genetic carrier | An unaffected heterozygote bearing a usually harmful recessive gene, a cancer that bears a dominant but latent age-dependent trait to have offspring with unbalanced karyotypes. (05 Mar 2000) |
| genetic code | <molecular biology> Relationship between the sequence of bases in nucleic acid and the order of amino acids in the polypeptide synthesised from it. A sequence of three nucleic acid bases (a triplet) acts as a codeword (codon) for one amino acid. (18 Nov 1997) |
| genetic colonisation | <molecular biology> The process of a parasite (such as a virus) inserting genes into a host's genome which cause the host cell to synthesise products that are only useful to the parasite. (07 May 1998) |
| genetic complement | <biology, genetics> The set of chromosomes contained within any one particular cell. (07 May 1998) |
| genetic complementation | <genetics> The reappearance of wild-type characteristics in a cell or organism that has had two distinct mutations on the same chromosome. Two normal versions of two different mutant genes on different chromosomes affecting the same phenotype which, when inherited together, results in the wild-type phenotype despite the presence of mutant copies of the genes.
