| melting temperature of DNA | That temperature at which, under a given set of conditions, double-stranded DNA is changed (50%) to single-stranded DNA; under standard conditions, the base composition of the DNA can be estimated from the denaturation temperature, since the greater the denaturation temperature, the greater the guanine-plus-cytosine content (i.e., GC content) of the DNA. Synonym: melting temperature of DNA. (05 Mar 2000) |

| permissive temperature | <molecular biology> Of a temperature sensitive mutation, a temperature at which the mutated gene product behaves normally and so the cell or organism survives as if wild type. C.f. The restrictive temperature, at which the gene product takes on a mutant phenotype. (18 Nov 1997) |
| room temperature | The ordinary temperature (65 |
| minimum temperature | In bacteriology, denoting a temperature below which growth will not take place. (05 Mar 2000) |
| critical temperature | The temperature of a gas above which it is no longer possible by use of any pressure, however great, to convert it into a liquid. (05 Mar 2000) |
| sensible temperature | The atmospheric temperature as felt by the individual, supposed to be that recorded by the wet-bulb thermometer. (05 Mar 2000) |
| standard temperature | A temperature of 0캜 or 273.15 |
| denaturation temperature of DNA | That temperature at which, under a given set of conditions, double-stranded DNA is changed (50%) to single-stranded DNA; under standard conditions, the base composition of the DNA can be estimated from the denaturation temperature, since the greater the denaturation temperature, the greater the guanine-plus-cytosine content (i.e., GC content) of the DNA. Synonym: melting temperature of DNA. (05 Mar 2000) |
| ignition temperature | <radiobiology> For given values of density and energy confinement, the temperature at which ignition occurs. (see ignition above) (09 Oct 1997) |
| optimum temperature | The temperature at which any operation, such as the culture of any special microorganism, is best carried on. (05 Mar 2000) |
| temperature | <chemistry> Temperature is proportional to the average random kinetic energy of ideal gases. (09 Jan 1998) |
| temperature coefficient | The fractional change in any physical property per degree rise in temperature. (05 Mar 2000) |
| temperature-compensated vaporiser | A vaporiser of liquid anaesthetics with graduated settings calibrated to deliver a known constant concentration of a specific anaesthetic despite changes in inflow volume and despite cooling brought about by vaporization. (05 Mar 2000) |
| temperature midpoint | The midpoint in the change in optical properties (absorbance, rotation) of a structured polymer (e.g., DNA) with increasing temperature. Synonym: melting temperature. (05 Mar 2000) |
| temperature, plasma | <radiobiology> A measure of the random (thermal) kinetic energy of the ions or electrons in the plasma. The temperature of each component of a plasma depends on the mean kinetic energy of that component. An example of this is the fluorescent light bulb, which is an example of a weakly-ionised plasma where the electrons are at temperatures of tens of thousands of degrees, whereas the ions and neutrals are much cooler (so that you can touch the bulb without being burned). See: atomic temperature, electron temperature, ion temperature. (09 Oct 1997) |
