complementarity
com·ple·men·tar·i·ty C0528900 (kŏm′plə-mĕn-tăr′ĭ-tē)n.1. The state or quality of being complementary.2. The proposition that the underlying properties of entities, especially subatomic particles, may manifest themselves in mutually exclusive forms at different times, depending on the conditions of the observation, and that any physical model that describes entities in terms of one form or the other will be incomplete.complementarity (ˌkɒmplɪmənˈtærɪtɪ) n, pl -ties1. a state or system that involves complementary components2. (General Physics) physics the principle that the complete description of a phenomenon in microphysics requires the use of two distinct theories that are complementary to each other.

complementarity[‚käm·plə·mən′tar·əd·ē] (quantum mechanics) The principle that nature has complementary aspects, particle and wave; the two aspects are related by p = h /λ and E = h ν, where p and E are the momentum and energy of the particle, λ and ν are the length and frequency of the wave, and h is Planck's constant. Complementarity in molecular biology, the mutual correspondence that makes for the connection between complementary structures (macromoiecules, molecules, radicals) and is determined by the chemical properties of the structures. According to J. Watson, complementarity is possible if the surfaces of the molecules have complementary structures, so that a protruding group or positive charge on one surface corresponds to a cavity or negative charge on the other; in other words, interacting molecules must fit one another like lock and key. The complementarity of chains of nucleic acids is based on the interaction of their nitrogenous bases. Thus, only when the arrangement is such that the adenine (A) in one chain is opposite the thymine (T) or uracyl (U) in the other and the guanine (G) in one is opposite the cytosine (C) in the other will there be hydrogen bonds between the bases of the chains. Complementarity seems to be the only and universal chemical mechanism for the storage and transmission of genetic information. Another example of complementarity is the interaction of an enzyme with its corresponding substrate. In immunology, the word “complementarity” refers to the relationship between an antigen and its corresponding antibodies. The term “complementarity” is sometimes used in biological literature in a sense that is closely related to the concept of complementation. REFERENCEWatson, J. Molekuliarnaia biologiia gena.
