| Haldane transformation | The multiplication of inspired oxygen concentration by the ratio of expired to inspired nitrogen concentrations in the calculation of oxygen consumption or respiratory quotient by the open circuit method. (05 Mar 2000) |
|---|
| Haldane chamber | An obsolete chamber for metabolic studies on animals. (05 Mar 2000) |
|---|---|
| Haldane effect | The promotion of carbon dioxide dissociation by oxygenation of haemoglobin. (05 Mar 2000) |
| Haldane, John B S | <person> English biochemist and geneticist, who wrote many works of popular science. Lived: 1892-1964. See: Haldane relationship. (05 Mar 2000) |
| Haldane, John S | <person> Scottish physiologist at Oxford. Lived: 1860-1936. See: Haldane's apparatus, Haldane chamber, Haldane effect, Haldane transformation, Haldane tube, Haldane-Priestley sample. (05 Mar 2000) |
| Haldane-Priestley sample | <physiology> An approximation of alveolar gas obtained from the end of a sudden maximal expiration into a Haldane tube. (05 Mar 2000) |
| Haldane relationship | <biochemistry> A mathematical relationship between the equilibrium constant of an enzyme-catalyzed reaction and all of that enzyme's kinetic parameters (e.g., Vmax and Km's). (05 Mar 2000) |
| Haldane's apparatus | <apparatus, chest medicine> A device used for the analysis of respiratory gases. (05 Mar 2000) |
| Haldane's evolutionary unit | <unit> A unit of measurement, given in darwins, which measures the increase in body size of a chronospecies over evolutionary time. (13 Nov 1997) |
| Haldane's rule | <genetics> if one of the two sexes is missing, sterile, or rare in a population of first-generation hybrids between two different species, then that sex is the heterogametic sex (has two different sex chromosomes, such as XY as opposed to XX). (09 Oct 1997) |
| Haldane tube | A tube for securing human alveolar air samples; consisting of a narrow hosepipe with a mouthpiece from which a tube is attached for the withdrawal of expired air at the end of a sudden, maximal expiration. (05 Mar 2000) |
| abiotic transformation | <biochemistry> An abiotic transformation is any process in which a chemical in the environment is altered by non-biological mechanisms (such as by exposure to sunlight). (09 Oct 1997) |
| bacterial transformation | <microbiology> A genetics lab procedure where bacteria are induced to accept and incorporate into their genome foreign pieces of cell-less, isolated DNA, often in the form of a plasmid. The DNA to be introduced usually contains a selectable marker so that the bacteria which successfully incorporate the DNA can be selected for. (09 Oct 1997) |
| blast transformation | <haematology> The morphological and biochemical changes in lymphocytes, both B and T, on exposure to antigen or to a mitogen. The cells appear to move from G0 to G1 stage of the cell cycle. They usually enlarge and proceed to S phase and mitosis later. The process probably involves receptor cross linking on the plasma membrane. (18 Nov 1997) |
| genetic transformation | <molecular biology> Genetic change brought about by the introduction of exogenous DNA into a cell. See: transformation, germ line transformation, transfection. (18 Nov 1997) |
| germ line transformation | Micro injection of foreign DNA into an early embryo, so that it becomes incorporated into the germ line of the individual and thus stably inherited in subsequent generations of transgenic organisms. Typically, the DNA would be a reporter gene or cDNA in a vector such as a transposon, that might also carry a visible marker gene such as eye or coat colour), so that successful transformation could readily be detected.
