| amber suppressor | <molecular biology> A tRNA molecule which suppresses amber mutations because it has mutated to recognise the amber codon UAG (which normally signals that the translation of mRNA into an amino acid chain should stop) as a signal for inserting whatever amino acid it carries into the chain. As a result, it can prevent the amino acid chain from ending before it is completed. (09 Oct 1997) |

| amber | 1. <chemical> A yellowish translucent resin resembling copal, found as a fossil in alluvial soils, with beds of lignite, or on the seashore in many places. It takes a fine polish, and is used for pipe mouthpieces, beads, etc, and as a basis for a fine varnish. By friction, it becomes strongly electric. 2. Amber colour, or anything amber-coloured; a clear light yellow; as, the amber of the sky. 3. Ambergris. "You that smell of amber at my charge." (Beau. & Fl) 4. The balsam, liquidambar. Black amber, and old and popular name for jet. Origin: OE. Aumbre, F. Ambre, Sp. Ambar, and with the Ar. Article, alambar, fr. Ar. 'anbar ambergris. Source: Websters Dictionary (01 Mar 1998) |

| amber codon | <molecular biology> One of the three terminator codons. Its sequence is UAG. See: ochre codon, opal codon. (18 Nov 1997) |
| amber fish | <zoology> A fish of the southern Atlantic coast (Seriola Carolinensis) Source: Websters Dictionary (01 Mar 1998) |
| amber mutant | A mutant with a mutation resulting in a UAG codon. (05 Mar 2000) |
| amber mutation | <molecular biology> A mutation from a codon which codes for an amino acid into the amber codon UAG, which normally signals that the translation of mRNA into an amino acid chain should stop. The mutation causes the amino acid chain to stop forming before it is actually completed. (09 Oct 1997) |
| amber seed | Seed of the Hibiscus abelmoschus, somewhat resembling millet, brought from Egypt and the West Indies, and having a flavor like that of musk; musk seed. Source: Websters Dictionary (01 Mar 1998) |
| amber tree | A species of Anthospermum, a shrub with evergreen leaves, which, when bruised, emit a fragrant odour. Source: Websters Dictionary (01 Mar 1998) |
| genes, suppressor | Genes that inhibit expression of a previous mutation. They allow the wild-type phenotype to be wholly or partially restored. (12 Dec 1998) |
| genes, suppressor, tumour | Genes that inhibit expression of the tumourigenic phenotype. They are normally involved in holding cellular growth in check. When tumour suppressor genes are inactivated or lost, a barrier to normal proliferation is removed and deregulated growth is possible. (12 Dec 1998) |
| suppressor | A compound that suppresses the effects of mutation or suppresses what would be a normal course of events. (05 Mar 2000) |
| suppressor cell | <immunology> Lymphocyte class of cells suppressing T or B antigen dependent responses. (18 Nov 1997) |
| suppressor cells | Cells of the immune system that inhibit or help to terminate an immune response, e.g., suppressor macrophages and suppressor T-cells. Synonym: cytotoxic cell. (05 Mar 2000) |
| suppressor factor | <immunology> Factors released by T suppressor cells. See: suppressor mutation, ochre suppressor, opal suppressor. (19 Jan 1998) |
| suppressor factors, immunologic | Proteins, protein complexes, or glycoproteins secreted by suppressor T-cells that inhibit either subsequent T-cells, B-cells, or other immunologic phenomena. Some of these factors have both histocompatibility (I-j) and antigen-specific domains which may be linked by disulfide bridges. They can be elicited by haptens or other antigens and may be mass-produced by hybridomas or monoclones in the laboratory. (12 Dec 1998) |
| suppressor mutation | <molecular biology> Mutation that alleviates the effect of a primary mutation at a different locus. May be through almost any mechanism that can give a primary mutation, but perhaps the most interesting class are the amber and ochre supressors, where the anticodon of the tRNA is altered so that it mis reads the termination codon and inserts an amino acid, preventing premature termination of the peptide chain.
