|---|---|
| alloplasty | Repair of defects by allotransplantation. (05 Mar 2000) |
| alloploid | Relating to a hybrid individual or cell with two or more sets of chromosomes derived from two different ancestral species; depending on the number of multiples of haploid sets, alloploid's are referred to as allodiploids, allotriploids, allotetraploids, allopentaploids, allohexaploids, etc. See: heterokaryon. Origin: allo-+ -ploid (05 Mar 2000) |
| alloploidy | The condition of being alloploid. (05 Mar 2000) |
| allopolyploid | <cell biology, genetics> A hybrid, usually a plant, which is created from two closely-related species and contains one or more extra sets of chromosomes (i.e. If each parent normally has two sets, the hybrid may have four). See: polyploid. (09 Oct 1997) |
| allopolyploidy | <genetics> Polyploid condition in which the contributing genomes are dissimilar. When the genomes are doubled fertility is restored and the organism is an amphidiploid. Common in plants but not animals. (18 Nov 1997) |
| allopregnane | Original name for 5alpha-pregnane. See: pregnane. (05 Mar 2000) |
| allopsychic | Denoting the mental processes in their relation to the outer world. Origin: allo-+ G. Psyche, mind (05 Mar 2000) |

| allosensitization | Exposure to an alloantigen that induces immunological memory cells. (05 Mar 2000) |
| allosome | <genetics> One or more chromosomes that can be distinguished from autosomes by their morphology and behaviour. Synonym: accessory chromosome, heterochromosome, sex chromosome. (18 Nov 1997) |
| allosteric | <biochemistry, chemistry> Of a binding site in a protein, usually an enzyme. The catalytic function of an enzyme may be modified by interaction with small molecules, not only at the active site, but also at a spatially distinct (allosteric) site of different specificity. Of a protein, a protein possessing such a site. An allosteric effector is a molecule bound at such a site that increases or decreases the activity of the enzyme. (18 Nov 1997) |
