| 설명 | 점이나 또는 평면에서 양쪽에 있는 부분이 똑같은 형으로 배치되어 있는 것. 점인 경우는 점대칭, 평면인 경우는 평면대칭이라 한다. 평면상에 두 개의 도형 F와 F-가 있을 때 F상의 점 P와 F-상의 점 P-를 대응시켜 대응하는 점 P와 P-를 연결하는 항상 하나의 정점 O로써 이등분된다면 도형 F와 F-는 점 O에 대하여 점대칭이다. 또한 평면상의 두 도형 F와 F-가 있을 때 F상의 점 P와 F-상의 점 P-를 대응시켜 대응하는 점 P와 P-를 연결한 선이 항상 일정한 직선1에 의해 수직 이등분되면 도형 F와 F-는 직선에 대해 선대칭이다. 같은 방법으로 공간에서의 면대칭을 정의할 수 있다. |

| bilateral symmetry | <biology> Describes an organism which is divisible into equal mirror halves in one plane only. (09 Oct 1997) |
| pseudo-symmetry | <chemistry> A kind of symmetry characteristic of certain crystals which from twinning, or other causes, come to resemble forms of a system other than that to which they belong, as the apparently hexagonal prisms of aragonite. Origin: Pseudo- + symmetry. Source: Websters Dictionary (01 Mar 1998) |
| symmetry | 1. A due proportion of the several parts of a body to each other; adaptation of the form or dimensions of the several parts of a thing to each other; the union and conformity of the members of a work to the whole. 2. <biology> The law of likeness; similarity of structure; regularity in form and arrangement; orderly and similar distribution of parts, such that an animal may be divided into parts which are structurally symmetrical. Bilateral symmetry, or two-sidedness, in vertebrates, etc, is that in which the body can be divided into symmetrical halves by a vertical plane passing through the middle; radial symmetry, as in echinoderms, is that in which the individual parts are arranged symmetrically around a central axis; serial symmetry, or zonal symmetry, as in earthworms, is that in which the segments or metameres of the body are disposed in a zonal manner one after the other in a longitudinal axis. This last is sometimes called metamerism. 3. <botany> Equality in the number of parts of the successive circles in a flower. Likeness in the form and size of floral organs of the same kind; regularity. Axis of symmetry. <geometry> See Axis. Respective symmetry, that disposition of parts in which only the opposite sides are equal to each other. Origin: L. Symmetria, Gr.; with, together + a measure: cf. F. Symetrie. See Syn-, and Meter rhythm. Source: Websters Dictionary (01 Mar 1998) |
| symmetry axis | <radiobiology> The straight line (usually vertical) through the centre of a configuration, when the configuration is symmetric to all (axisymmetric, like the tokamak) or some (periodic, like the stellarator) rotations about this line. Usually the z-axis. (09 Oct 1997) |
| dyad symmetry element | Dyad symmetry element bound by serum response factor to control the expression of c fos. (18 Nov 1997) |
| dyad symmetry of DNA | <molecular biology> Two areas of a DNA molecule whose base pair sequences are repeats of each other, inverted relative to each other, or are palindromes. (09 Oct 1997) |
| inverse symmetry | Correspondence of the right or left side of an asymmetrical individual to the left or right side of another. (05 Mar 2000) |
| adenosine 3',5'-cyclic monophosphate | An activator of phosphorylase kinase and an effector of other enzymes, formed in muscle from ATP by adenylate cyclase and broken down to 5'-AMP by a phosphodiesterase; sometimes referred to as the "second messenger." A related compound (2',3') is also known. Synonym: cyclic adenylic acid, cyclic AMP, cyclic phosphate. Acronym: cAMP (05 Mar 2000) |
| adenosine 3',5'-cyclic phosphate phosphodiesterase | <enzyme> An enzyme that catalyses the hydrolysis of adenosine 3',5'-cyclic phosphate forming 5'-AMP. A crucial step in the regulation of cellular adenosine 3',5'-cyclic phosphate levels. Inhibited by caffeine. Synonym: cAMP phosphodiesterase. (05 Mar 2000) |
| adenosine cyclic phosphate | An activator of phosphorylase kinase and an effector of other enzymes, formed in muscle from ATP by adenylate cyclase and broken down to 5'-AMP by a phosphodiesterase; sometimes referred to as the "second messenger." A related compound (2',3') is also known. Synonym: cyclic adenylic acid, cyclic AMP, cyclic phosphate. Acronym: cAMP (05 Mar 2000) |
| amino acids, cyclic | A class of amino acids characterised by a closed ring structure. (12 Dec 1998) |
| canine infectious cyclic thrombocytopenia | An infection of dogs with the rickettsia Ehrlichia platys characterised by recurrent cyclic thrombocytopenia. (05 Mar 2000) |
| receptors, cyclic AMP | Cell surface proteins that bind cyclic AMP with high affinity and trigger intracellular changes which influence the behaviour of cells. The best characterised cyclic AMP receptors are those of the slime mold dictyostelium discoideum. The transcription regulator cyclic AMP receptor protein of prokaryotes is not included nor are the eukaryotic cytoplasmic cyclic AMP receptor proteins which are the regulatory subunits of cyclic AMP-dependent protein kinases. (12 Dec 1998) |
| cyclic | <chemistry> Pertaining to or occurring in a cycle or cycles, the term is applied to chemical compounds that contain a ring of atoms in the nucleus. Origin: Gr. Kyklikos (18 Nov 1997) |
