| symbol | 1. A visible sign or representation of an idea; anything which suggests an idea or quality, or another thing, as by resemblance or by convention; an emblem; a representation; a type; a figure; as, the lion is the symbol of courage; the lamb is the symbol of meekness or patience. "A symbol is a sign included in the idea which it represents, e.g, an actual part chosen to represent the whole, or a lower form or species used as the representative of a higher in the same kind." (Coleridge) 2. <mathematics> Any character used to represent a quantity, an operation, a relation, or an abbreviation. In crystallography, the symbol of a plane is the numerical expression which defines its position relatively to the assumed axes. 3. An abstract or compendium of faith or doctrine; a creed, or a summary of the articles of religion. 4. [Gr. Contributions] That which is thrown into a common fund; hence, an appointed or accustomed duty. "They do their work in the days of peace . . . And come to pay their symbol in a war or in a plague." (Jer. Taylor) 5. Share; allotment. "The persons who are to be judged . . . Shall all appear to receive their symbol." (Jer. Taylor) 6. <chemistry> An abbreviation standing for the name of an element and consisting of the initial letter of the Latin or new Latin name, or sometimes of the initial letter with a following one; as, C for carbon, Na for sodium (Natrium), Fe for iron (Ferrum), Sn for tin (Stannum), Sb for antimony (Stibium), etc. See the list of names and symbols under Element. In pure and organic chemistry there are symbols not only for the elements, but also for their grouping in formulas, radicals, or residues, as evidenced by their composition, reactions, synthesis, etc. See the diagram of Benzene nucleus, under Benzene. Synonym: Emblem, figure, type. See Emblem. Origin: L. Symbolus, symbolum, Gr. A sign by which one knows or infers a thing, from to throw or put together, to compare; with + to throw: cf. F. Symbole. Cf. Emblem, Parable. Source: Websters Dictionary (01 Mar 1998) |

| genetic code | <molecular biology> Relationship between the sequence of bases in nucleic acid and the order of amino acids in the polypeptide synthesised from it. A sequence of three nucleic acid bases (a triplet) acts as a codeword (codon) for one amino acid. (18 Nov 1997) |
| code | The genetic code is the correspondence between the triplet of bases in DNA with the amino acids. The discovery of the genetic code clearly ranks as one of the premiere events of what has been called the Golden Age of Biology (and Medicine). (12 Dec 1998) |
| soundex code | A sequence of letters used for recording names phonetically, especially in record linkage. (05 Mar 2000) |
| Strickland code | <zoology> A code of nomenclature for taxonomic classification prepared by a committee of the British Association for the Advancement of Science, first published in 1842. (09 Jan 1998) |
| degenerate code | <molecular biology> The fact that in most cases in the genetic code used by all life on Earth, one particular amino acid is specified by more than one three-base combination of the four nitrogenous bases (called a codon). There are enough different codons to specify 64 different amino acids, but there are in actuality only 20 amino acids (and three stop codons) used in the making of proteins. (09 Oct 1997) |
| International Code of Zoological Nomenclature | <zoology> An Authoritative document containing a system of rules and recommendations to be followed in giving a scientific name to an animal or animal group. Adopted by the International Congresses of Zoology and Administered by the International Commission on Zoological Nomenclature. The most recent version of the Code, adopted in principle by the 20th General Assembly of the International Union of Biological Sciences at Helsinki in 1979, was approved by the ICZN late in 1983. With minor exceptions it retains the same format as the first two editions. Minor amendments for immediate incorporation are published in Bulletin Zoological Nomenclature as Declarations to remain in force until ratified or rejected by future congresses. (09 Jan 1998) |
| uniform mechanical code | (UMC) A code sponsored by the International Association of Plumbing and Mechanical Officials and the International Conference of Building Officials, adopted and amended by the Oregon Department of Commerce. The UMC contains requirements for the installation and maintenance of heating, ventilating, cooling, and refrigeration systems. (05 Dec 1998) |
| bufadienolides (two double bonds) | Bufatrienolides (three double bonds), etc; they have varying numbers of hydroxyl groups at positions 3, 5, 14, and 16, and these may be further substituted. For structure, see steroids. (05 Mar 2000) |
| gel diffusion precipitin tests in two dimensions | Precipitin test's made in a layer of agar that permits radial diffusion, in both of the horizontal dimensions, of one or both reactants. Double (gel) diffusion in two dimensions (Ouchterlony test, technique, or method) incorporates antigen and antibody solutions placed in separate wells in a sheet of plain agar, permitting radial diffusion of both reactants; this method is widely used to determine antigenic relationships; the bands of precipitate that form where the reactants meet in optimal concentration are of three patterns, referred to as reaction of identity, reaction of partial identity (cross-reaction), and reaction of nonidentity. (05 Mar 2000) |
| Master's two-step exercise test | An early and long-used exercise challenge to identify ischemic heart disease using a pair of nine inch steps with a platform on top, the number of trips by the patient arbitrarily chosen and related to age and body weight. See: two-step exercise test. Synonym: Master's two-step exercise test. (05 Mar 2000) |
| immunoelectrophoresis, two-dimensional | Immunoelectrophoresis in which a second electrophoretic transport is performed on the initially separated antigen fragments into an antibody-containing medium in a direction perpendicular to the first electrophoresis. (12 Dec 1998) |
| electrophoresis, gel, two-dimensional | Electrophoresis in which a second perpendicular electrophoretic transport is performed on the separate components resulting from the first electrophoresis. This technique is usually performed on polyacrylamide gels. (12 Dec 1998) |
| two | One and one; twice one. "Two great lights." . "Two black clouds." Two is often joined with other words, forming compounds signifying divided into, consisting of, or having, two parts, divisions, organs, or the like; as two-bladed, two-celled, two-eared, two-flowered, twohand, two-headed, two-horse, two-leafed or two-leaved, two-legged, two-lobed, two-masted, two-named, two-part, two-petaled, two-pronged, two-seeded, two-sided, two-story, two-stringed, two-foothed, two-valved, two-winged, and the like. One or two, a phrase often used indefinitely for a small number. Source: Websters Dictionary (01 Mar 1998) |
| two-bellied muscle | <anatomy> One of the suprahyoid group of muscles consisting of two bellies united by a central tendon which is connected to the body of the hyoid bone; origin, by posterior belly from the digastric groove medial to the mastoid process; insertion, by anterior belly into lower border of mandible near midline; action, elevates the hyoid when mandible is fixed; depresses the mandible when hyoid is fixed; nerve supply, posterior belly from facial, anterior belly by nerve to the mylohyoid from the mandibular division of trigeminal, a muscle with two fleshy bellies separated by a fibrous insertion. Synonym: musculus digastricus, biventer mandibulae, musculus biventer mandibulae, two-bellied muscle. (05 Mar 2000) |
