| genetic material | A gene, a part of a gene, a group of genes, or fragments of many genes, on a molecule of DNA, a fragment of DNA, a group of DNA molecules, or fragments of many DNA molecules. Could refer to anything from a small fragment of DNA to the entire genome of an organism. (09 Oct 1997) |
|---|---|
| genetic model | A formalised conjecture about the behaviour of a heritable structure in which the component terms are intended to have literal interpretation as standard structures of empirical genetics. (05 Mar 2000) |
| genetic penetrance | The extent to which a genetically determined condition is expressed in an individual. (05 Mar 2000) |
| genetic polymorphism | The occurrence in the same population of multiple discrete alletic states of which at least two have high frequency (conventionally of 1% or more). (05 Mar 2000) |
| genetic psychology | A science dealing with the evolution of behaviour and the relation to each other of the different types of mental activity. (05 Mar 2000) |
| genetic recombination | <molecular biology> Formation of new combinations of alleles in offspring (viruses, cells or organisms) as a result of exchange of DNA sequences between molecules. It occurs naturally, as in crossing over between homologous chromosomes in meiosis or experimentally, as a result of genetic engineering techniques. (18 Nov 1997) |
| genetic screening | The process of testing individuals to find out if they carry genes for certain known genetic diseases, such as sickle cell anaemia. (09 Oct 1997) |
| genetic techniques | Chromosomal, biochemical, intracellular, and other methods used in the study of genetics. (12 Dec 1998) |
| genetic toxicology | <study> This is the study of chemicals which can damage the genetic structure of living organisms (including humans) and thus cause problems such as mutations, cancer and birth defects. (09 Oct 1997) |
| genetic transformation | <molecular biology> Genetic change brought about by the introduction of exogenous DNA into a cell. See: transformation, germ line transformation, transfection. (18 Nov 1997) |
| genetic variance | Within a population, the measure of how much of the variation of a particular phenotype is due to genotypic variation (as opposed to environmental factors. An example might be the height of a human as determined by genes inherited from the human's parents. See: environmental variance. (09 Oct 1997) |
| genetic vectors | Plasmids, bacteriophages, or viruses used during recombinant DNA techniques that transport foreign genes into recipient cells. Genetic vectors possess a functional replicator site and contain a genetic marker to facilitate their selective recognition. (12 Dec 1998) |
| recombination, genetic | Production of new arrangements of genes by various mechanisms such as assortment and segregation, crossing over, gene conversion, transformation, conjugation, transduction, f-duction, or mixed infection of viruses. (12 Dec 1998) |
| mobile genetic element | <molecular biology> Small, mobile DNA sequences that can replicate and insert copies at random sites within chromosomes. They have nearly identical sequences at each end, oppositely oriented (inverted) repeats and code for the enzyme, transposase, that catalyses their insertion. Bacteria have two types of transposon, simple transposons that have only the genes needed for insertion and complex transposons that contain genes in addition to those needed for insertion. Eukaryotes contain two classes of mobile genetic elements, the first are like bacterial transposons in that DNA sequences move directly. The second class (retrotransposons) move by producing RNA that is transcribed, by reverse transcriptase, into DNA which is then inserted at a new site. (13 Nov 1997) |
| models, genetic | Theoretical representations that simulate the behaviour or activity of genetic processes or phenomena. They include the use of mathematical equations, computers, and other electronic equipment. (12 Dec 1998) |
