| recon | the smallest unit of DNA capable of recombination [recombination + Gr. on quantum] |
| ss(c)DNA | single-stranded circular deoxyribonucleic acid |

statistical analysis
| cost-benefit analysis | A method of comparing the cost of a program with its expected benefits in dollars (or other currency). The benefit-to-cost ratio is a measure of total return expected per unit of money spent. This analysis generally excludes consideration of factors that are not measured ultimately in economic terms. Cost effectiveness compares alternative ways to achieve a specific set of results. (12 Dec 1998) |
|---|---|
| costs and cost analysis | Absolute, comparative, or differential costs pertaining to services, institutions, resources, etc., or the analysis and study of these costs. (12 Dec 1998) |
| half-tetrad analysis | <genetics> The analysis of tetrad chromosomes (a pair of homologous chromosomes, thus four total chromosomes) after recombination when only half of the tetrad (two of the four chromosomes) can be analysed. (13 Nov 1997) |
| predisposition analysis | <genetics> The analysis of how some people are more likely to get certain diseases as a result of their genetic make-up. (31 Dec 1997) |
| saturation analysis | General term for an assay in which a binder competes for labelled versus unlabelled ligand; following separation of free and bound ligand, the ligand (the analyte assayed) is quantitated by relating bound and unbound ratios to known standards. See: enzyme-linked immunosorbent assay, radioreceptor assay, immunoassay, enzyme-multiplied immunoassay technique, radioimmunoassay. Synonym: displacement analysis, saturation analysis. (05 Mar 2000) |
| proximate analysis | An analysis which reports volatile matter, fixed carbon, moisture content, and ash present in a fuel as a percentage of dry fuel weight. (05 Dec 1998) |
| segregation analysis | In genetics, the enumeration of progeny according to distinct and mutually exclusive phenotypes; used as a test of a putative pattern of inheritance, e.g., mendelian, dominant autosomal, epistatic, age-dependent. (05 Mar 2000) |
| self-analysis | Attempted analysis, or psychoanalysis, of one's self. Synonym: self-analysis. (05 Mar 2000) |
| semen analysis | <gynaecology> Laboratory examination of semen to check the quality and quantity of sperm. (09 Oct 1997) |
| sequence analysis | A multistage process that includes the determination of a sequence (protein, carbohydrate, etc.), its fragmentation and analysis, and the interpretation of the resulting sequence information. This information is useful in that it: 1) reveals the similarities of homologous genes, thereby providing insight into the possible regulation and functions of these genes; and 2) leads to a better understanding of disease states related to genetic variation. New sequencing methodologies, fully automated instrumentation, and improvements in sequencing-related computational resources contribute to the potential for genome-size sequencing projects. (12 Dec 1998) |
| sequence analysis, RNA | A multistage process that includes RNA cloning, physical mapping, subcloning, sequencing, and information analysis. (12 Dec 1998) |
| sequential analysis | A statistical method that allows an experiment to be ended as soon as a result of desired precision is obtained. (05 Mar 2000) |
| sex determination (analysis) | Validation of the sex of an individual by inspection of the gonads and/or by genetic tests. (12 Dec 1998) |
| small-area analysis | A method of analyzing the variation in utilization of health care in small geographic or demographic areas. It often studies, for example, the usage rates for a given service or procedure in several small areas, documenting the variation among the areas. By comparing high- and low-use areas, the analysis attempts to determine whether there is a pattern to such use and to identify variables that are associated with and contribute to the variation. (12 Dec 1998) |
| Southern blot analysis | A procedure to separate and identify DNA sequences; DNA fragments are separated by electrophoresis on an agarose gel, transferred (blotted) onto a nitrocellulose or nylon membrane, and hybridised with complementary (labelled) nucleic acid probes. (05 Mar 2000) |
