| 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, DNA | A multistage process that includes DNA cloning, physical mapping, subcloning, sequencing, and information analysis. New technological advances have led to the automation of certain steps in this process and contribute to the potential for large-scale DNA sequencing efforts. (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) |
| sputum analysis | A method of detecting certain infections (especially tuberculosis) by culturing of sputum, the mucus matter that collects in the respiratory and upper digestive passages and is expelled by coughing. (09 Oct 1997) |
| stratographic analysis | A former term for chromatography. (05 Mar 2000) |
| neutron activation analysis | Activation analysis in which the specimen is bombarded with neutrons. Identification is made by measuring the resulting radioisotopes. (12 Dec 1998) |
| structure activity analysis | Study in which systematic variation in the structure of a compound is correlated with its activity, in an attempt to determine the characteristics of the (receptor) site at which it acts. (18 Nov 1997) |
| Northern blot analysis | A procedure similar to the Southern blot analysis, used mostly to separate and identify RNA fragments; typically via transferring RNA fragments from an agarose gel to a nitrocellulose filter followed by detection with a suitable probe. Origin: coined to distinguish it from eponymic Southern blot a. (05 Mar 2000) |
