| 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).

|---|---|
| trans Golgi network | <cell biology> A complex of membranous tubules and vesicles, near the trans face of the Golgi, which is thought to be a major intersection for intracellular traffic of vesicles. (18 Nov 1997) |
| trans-Golgi reticulum | That part of the Golgi apparatus that takes newly processed proteins and delivers them to secretory vesicles that will fuse with other biomembranes (e.g., the plasma membrane). (05 Mar 2000) |
| trans-octaprenyltranstransferase | <enzyme> Level of isopentenyl diphosphate-magnesium(ipp-mg) is decisive in affecting the chain length of the products of prenyltransferase reaction Registry number: EC 2.5.1.11 Synonym: solanesyl diphosphate synthase, solanesyl pyrophosphate synthetase (26 Jun 1999) |
| trans-pentaprenyltranstransferase | <enzyme> From micrococcus luteus b-p26; composed of 2 components; requires all-trans farnesyl or all-trans-geranylgeranyl pyrophosphate Registry number: EC 2.5.1.33 Synonym: all-trans-hexaprenylpyrophosphate synthase, hexaprenyldiphosphate synthetase, trans-pentaprenyltransferase, hexaprenylpyrophosphate synthetase (26 Jun 1999) |
| trans-retinal | The orange retinaldehyde resulting from the action of light on the rhodopsin of the retina, which converts the 11-cis-retinal component of the rhodopsin to all-trans-retinal plus opsin. Synonym: trans-retinal, visual yellow. (05 Mar 2000) |
| trans splicing | <molecular biology> Relating to RNA splicing of two different pre mRNA molecules together. Seems to rely on intron like sequences. Contrasts with the normal cis splicing of conventional RNA molecules. (19 Jan 1998) |
| trans-splicing | Formation of spliced products containing portions of two different transcripts. (05 Mar 2000) |
| advanced life support | Definitive emergency medical care that includes defibrillation, airway management, and use of drugs and medications. Compare: basic life support. (05 Mar 2000) |
| artificial life | Artificial life (AL, alife) is a scientific discipline in whichresearchers study life by creating computer programs that recreatebiological systems from scratch. (09 Oct 1997) |
| basic life support | Emergency cardiopulmonary resuscitation, control of bleeding, treatment of shock, acidosis, and poisoning, stabilization of injuries and wounds, and basic first aid. (05 Mar 2000) |
| biological half-life | <biochemistry, biology> This is the time required for one-half of the total amount of a particular substance in a biological system to be consumed or broken down by biological processes when the rate of removal is approximately exponential. Toxic chemicals with a long biological half-life (such as some pesticides) will tend to accumulate in the body and are, therefore, more likely to be harmful. A substance with a short biological half-life may still accumulate if a portion of it it becomes tightly bound to bone or other tissues, even if most of it is quickly cleared from the body. (21 Mar 1998) |
| vegetative life | The simple metabolic and reproductive activity of humans or animals, apart from the exercise of conscious mental or psychic processes. (05 Mar 2000) |
| germ-free life | Animals not contaminated by or associated with any foreign organisms. (12 Dec 1998) |
| change of life | Colloquialism for menopause, climacteric. (05 Mar 2000) |
