| degenerate | Having become worse than one's kind, or one's former state; having declined in worth; having lost in goodness; deteriorated; degraded; unworthy; base; low. "Faint-hearted and degenerate king." (Shak) "A degenerate and degraded state." (Milton) "Degenerate from their ancient blood." (Swift) "These degenerate days." (Pope) "I had planted thee a noble vine . ., how then art thou turned into the degenerate plant of a strange vine unto me?" (Jer. Ii. 21) Origin: L. Degeneratus, p. P. Of degenerare to degenerate, cause to degenerate, fr. Degener base, degenerate, that departs from its race or kind; de- + genus race, kind. See Kin relationship. 1. To be or grow worse than one's kind, or than one was originally; hence, to be inferior; to grow poorer, meaner, or more vicious; to decline in good qualities; to deteriorate. "When wit transgresseth decency, it degenerates into insolence and impiety." (Tillotson) 2. <biology> To fall off from the normal quality or the healthy structure of its kind; to become of a lower type. Origin: Degenerated; Degenerating.

| degenerate code | <molecular biology> The fact that in most cases in the genetic code used by all life on Earth, one particular amino acid is specified by more than one three-base combination of the four nitrogenous bases (called a codon). There are enough different codons to specify 64 different amino acids, but there are in actuality only 20 amino acids (and three stop codons) used in the making of proteins. (09 Oct 1997) |
| absolute configuration | <chemistry> The three-dimensional arrangement of the atoms around the chiral centre of a molecule. (09 Oct 1997) |
| cis configuration | <molecular biology> The configuration of an organic molecule containing a double bond between two carbon atoms, where the largest, most complex R groups are on the same side: H H \ / C=C / \ H3C CH3 -OR-The configuration of an organic molecule containing a ring, where the largest, most complex R groups are on the same side: H H | ___ \ / | // \\ [ring viewed edge-on] | \___/ / \ | /---\ H3C CH3 | H3C CH3. A genetics term meaning an event or a gene whose action occurs on the same chromosome. Two mutations in different genes coding for the same phenotype which are on the same chromosome (as opposed to the trans configuration where each homologue has one of the mutations). Compare: trans configuration. (11 Jan 1998) |
| configuration | <chemistry> The three-dimensional arrangement of an organic molecule that is caused by: double bonds that prevent free rotation, or chiral centres that haveside groups arranged around them in a particular order. A configurational isomer cannot be turned into another configuration without breaking covalent bonds. (09 Oct 1997) |
| stereochemical configuration | <chemistry> The arrangement of atoms in a molecule in three-dimensional space, especially with regard to the differences between enantiomers. The arrangements are specified in chemical formulas with the letters R, S, L, and/or D. In the R, S system, each asymmetric carbon atom is classified as R (for rectus, Latin for right) if the chemical groups attached to it have decreasing priorities in a clockwise direction, or S (for sinister, Latin for left) if the chemical groups attached to it have decreasing priorities in a counterclockwise direction, when the carbon atom in question is viewed along the bond of the chemical group with the lowest priority. Priorities are assigned to chemical groups according to the Cahn-Ingold Prelog priority rules (generally, the larger the group the higher the priority). L and D designations are given if the enantiomers have optical activity, that is, if they will rotate polarized light. The member of the pair which rotates polarized light clockwise is dextrorotatory, or D, and the member of the pair which rotates polarized light counterclockwise is levorotatory, or L (there is always one of each in every pair). This is also often referred to as handedness, where D is right-handed and L is lefthanded. (13 Nov 1997) |
| trans configuration | 1. <chemistry> The configuration of an organic molecule containing a double bond between two carbon atoms, where the largest, most complex R groups attached to each carbon are on opposite sides. Alternatively: The configuration of an organic molecule containing a ring, where the largest, most complex R groups attached to each carbon are on opposite sides. These configurations are the opposite of cis configuration. 2. <genetics> A genetics term meaning that the changes in gene expression are due to something acting on the gene from a distance, or from an unrelated location, rather than on the same strand of DNA. Two mutations in different genes coding for the same phenotype which are on opposite homologous chromosomes (as opposed to the cis configuration where both of the mutations are on the same homologue). (17 Mar 1998) |
| field-reversed configuration | <radiobiology> A compact torus produced in a theta pinch and having (in principle) no toroidal field. The potential advantages for a fusion reactor include a simple (linear) machine geometry, an average plasma pressure close to the confining field pressure, and physical separation of formation and burn chambers. The are predicted to be violently unstable to tilting, but this is rarely observed. (09 Oct 1997) |
