| 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 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 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 tree | A species of Anthospermum, a shrub with evergreen leaves, which, when bruised, emit a fragrant odour. Source: Websters Dictionary (01 Mar 1998) |
| active mutant | A mutant with overt phenotypic expression. (05 Mar 2000) |
| auxotrophic mutant | Mutant with a nutritional requirement not present in the wild type organism. Synonym: defective organism, deficiency mutant. (05 Mar 2000) |
| gap mutant | <molecular biology> A fruit fly of the genus Drosophila which is missing a number of adjacent segments because the segments failed to develop. (09 Oct 1997) |
| rats, mutant strains | Rats bearing mutant genes which are phenotypically expressed in the animals. (12 Dec 1998) |
| virulent phage mutant | A mutant of a phage that is unable to establish lysogeny. (05 Mar 2000) |
| relaxed mutant | A mutant bacterium that continues to synthesise RNA in a medium that lackscertain nutrients or amino acids which that sort of bacterium normallyneeds present before it can make RNA. (09 Oct 1997) |
| ced mutant | <organism> Giant multinucleate fresh water amoeba (up to 5mm long) much used for studies on the mechanism of cell locomotion. (18 Nov 1997) |
| cell division cycle mutant | A yeast cell which has cell division cycle genes that have mutated to become sensitive to temperature, at certain temperatures (usually high ones), various parts of the normal yeast cell cycle become abnormal, and in some strains the yeast cell does not survive at all.
