| gene markers | Detectable genetic traits or distinctive segments of DNA that serve as landmarks for a target gene. Markers are on the same chromosome as the target gene. They must be near enough to the target gene to be genetically linked to it: to be inherited usually together with that gene, and so serve as signposts to it. (12 Dec 1998) |
|---|---|
| gene mosaicism | <genetics> Descriptive of an organism that consists of two or more genetically distinct cell lines. (14 Nov 1997) |
| gene pool | The total sum of genetic information present in a population at anygiven moment. (09 Oct 1997) |
| gene probe | A biomolecule that islabelled with radioactive isotopes or with a fluorescent marker that selectively binds to a specific gene so it can be isolated or identified. (09 Oct 1997) |
| gene product | The biochemical material, either RNA or protein, resulting from expression of a gene. The amount of gene product is used to measure how active a gene is, abnormal amounts can be correlated with disease-causing alleles. (09 Oct 1997) |
| gene rearrangement | A structural alteration of a chromosome that causes a change in the orderof its loci. (09 Oct 1997) |
| gene rearrangement, alpha-chain T-cell antigen receptor | Ordered rearrangement of T-cell variable gene regions coding for the alpha-chain of antigen receptors. (12 Dec 1998) |
| gene rearrangement, beta-chain T-cell antigen receptor | Ordered rearrangement of T-cell variable gene regions coding for the beta-chain of antigen receptors. (12 Dec 1998) |
| gene rearrangement, b-lymphocyte | Ordered rearrangement of b-lymphocyte variable gene regions coding for the immunoglobulin chains, thereby contributing to antibody diversity. It occurs during the differentiation of the immature b-lymphocyte. (12 Dec 1998) |
| gene rearrangement, b-lymphocyte, heavy chain | Ordered rearrangement of b-lymphocyte variable gene regions thereby contributing to antibody diversity. It occurs during the first stage of differentiation of the immature b-lymphocyte. (12 Dec 1998) |
| gene rearrangement, b-lymphocyte, light chain | Ordered rearrangement of b-lymphocyte variable gene regions coding for the kappa or lambda light chains, thereby contributing to antibody diversity. It occurs during the second stage of differentiation of the immature b-lymphocyte. (12 Dec 1998) |
| gene rearrangement, delta-chain T-cell antigen receptor | Ordered rearrangement of T-cell variable gene regions coding for the delta-chain of antigen receptors. (12 Dec 1998) |
| gene rearrangement, gamma-chain T-cell antigen receptor | Ordered rearrangement of T-cell variable gene regions coding for the gamma-chain of antigen receptors. (12 Dec 1998) |
| gene rearrangement, t-lymphocyte | Ordered rearrangement of T-cell variable gene regions coding for the antigen receptors. (12 Dec 1998) |
| gene redundancy | A situation in which many copies of the same gene exist in a genome. (09 Oct 1997) |
