| HMW | High Molecular Weight |
D factor
| terminator regions (genetics) | DNA sequences which signal the termination of transcription. (12 Dec 1998) |
|---|---|
| trans-activation (genetics) | Increased rate of gene expression directed by either viral or cellular proteins. These regulatory factors (diffusible gene products) act in trans -- that is, act on homologous or heterologous molecules of DNA. (cis-acting factors act only on homologous molecules.) (12 Dec 1998) |
| translocation (genetics) | A type of aberration characterised by fragmentation of a chromosome and transfer of the broken-off portion to another chromosome, often of a different pair. (12 Dec 1998) |
| transplantation genetics | Genetics as applied to the transplanting of tissues from one animal to another. (05 Mar 2000) |
| epidemiological genetics | The study of genetics as a phenomenon of defined populations by the criteria, methods, and objectives of epidemiology rather than of population genetics. (05 Mar 2000) |
| relative molecular mass | The sum of the atomic weight's of all the atoms constituting a molecule; the mass of a molecule relative to the mass of a standard atom, now 12C (taken as 12.000). Relative molecular mass (Mr) is the mass relative to the dalton and has no units. See: atomic weight. Synonym: molecular mass, molecular weight ratio, relative molecular mass. (05 Mar 2000) |
| gram-molecular weight | Molecular weight expressed in grams. Compare: mole. (05 Mar 2000) |
| cloning, molecular | The insertion of recombinant DNA molecules from prokaryotic and/or eukaryotic sources into a replicating vehicle, such as a plasmid or virus vector, and the introduction of the resultant hybrid molecules into recipient cells without altering the viability of those cells. (12 Dec 1998) |
| models, molecular | Models used experimentally or theoretically to study molecular shape, electronic properties, or interactions; includes analogous molecules, computer-generated graphics, and mechanical structures. (12 Dec 1998) |
| molecular | <chemistry> Of, pertaining to or composed of molecules: a very small mass of matter. (18 Nov 1997) |
| molecular behaviour | <psychology> Behaviour described in small response units rather than larger ones; a specific response. Compare: molar behaviour. (05 Mar 2000) |
| molecular biophysics | Biophysics concerned with membrane processes, conformational and configurational properties of macromolecules, bioelectrical phenomena, etc. (05 Mar 2000) |
| molecular chaperones | A family of cellular proteins that mediate the correct assembly or disassembly of other polypeptides, and in some cases their assembly into oligomeric structures, but which are not components of those final structures. It is believed that chaperone proteins assist polypeptides to self-assemble by inhibiting alternative assembly pathways that produce nonfunctional structures. Some classes of molecular chaperones are the nucleoplasmins, the chaperonins, the heat-shock proteins 70, and the heat-shock proteins 90. (12 Dec 1998) |
| molecular clock | This term has two separate uses. 1. <molecular biology> The rate of fixation of mutations in DNA and thus times the rate of genetic diversification. 2. <cell biology> A biological system capable of maintaining up a timing rhythm or pulse. All such clocks are thought to be entrained by a natural oscillator such as the diurnal rhythm. (18 Nov 1997) |
| molecular cloning | <molecular biology> The biological amplification of a specific DNA sequence through mitotic division of a host cell into which it has been transformed or transfected. (09 Oct 1997) |
