  • (20) Enzymatic data for those ICR-191A-induced revertants of hisD3018 arising within the hisD gene indicate that the enzyme is wild type and, therefore, that ICR-191A can cause deletions as well as additions of single base pairs.

System


Definition:

  • (n.) An assemblage of objects arranged in regular subordination, or after some distinct method, usually logical or scientific; a complete whole of objects related by some common law, principle, or end; a complete exhibition of essential principles or facts, arranged in a rational dependence or connection; a regular union of principles or parts forming one entire thing; as, a system of philosophy; a system of government; a system of divinity; a system of botany or chemistry; a military system; the solar system.

  • (n.) An assemblage of parts or organs, either in animal or plant, essential to the performance of some particular function or functions which as a rule are of greater complexity than those manifested by a single organ; as, the capillary system, the muscular system, the digestive system, etc.; hence, the whole body as a functional unity.
  • (n.) One of the stellate or irregular clusters of intimately united zooids which are imbedded in, or scattered over, the surface of the common tissue of many compound ascidians.
