| melting temperature | 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) |

| 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) |
| melting | Liquefaction; the act of causing (something) to melt, or the process of becoming melted. <chemistry> Melting point, the degree of temperature at which a solid substance melts or fuses; as, the melting point of ice is 0 deg Centigrade or 32 deg Fahr, that of urea is 132 deg Centigrade. Melting pot, a vessel in which anything is melted; a crucible. Source: Websters Dictionary (01 Mar 1998) |
|---|---|
| melting point | The temperature at which a solid becomes a liquid, the temperature at which 50% of a macromolecule becomes denatured. (05 Mar 2000) |
| melting sign | <radiology> Regression of consolidation from periphery to centre, seen in pulmonary infarction, appears within days to weeks (12 Dec 1998) |
| DNA melting | <molecular biology> Denaturation of a DNA molecule with heat. The double-stranded molecule breaks up into two single-stranded molecules as a result of heat. (09 Oct 1997) |
| thermal melting profile | In general a record of the phase state of a system over a temperature range. Phase changes can be detected by exothermy or endothermy. Valuable in studying lipid and DNA structures. (18 Nov 1997) |
| absolute temperature | Temperature reckoned in Kelvins from absolute zero. (05 Mar 2000) |
| basal body temperature | <biology> The temperature taken at its lowest point in the day, usually in the morning before getting out of bed. (09 Oct 1997) |
| body temperature changes | Any deviation from normal body temperature of the human body, about 98.6 degrees f. Or 37 degrees c. When taken orally. (12 Dec 1998) |
| maximum temperature | In bacteriology, denoting a temperature above which growth will not take place. (05 Mar 2000) |
| mean temperature | The average atmospheric temperature in any locality for a designated period of time, as a month or a year. (05 Mar 2000) |
| restrictive 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) |
| 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) |
