Machinery
Definition:
(n.) Machines, in general, or collectively.
(n.) The working parts of a machine, engine, or instrument; as, the machinery of a watch.
(n.) The supernatural means by which the action of a poetic or fictitious work is carried on and brought to a catastrophe; in an extended sense, the contrivances by which the crises and conclusion of a fictitious narrative, in prose or verse, are effected.
(n.) The means and appliances by which anything is kept in action or a desired result is obtained; a complex system of parts adapted to a purpose.
Example Sentences:
(1) It is argued that this process drove the evolution of present 5' and 3' splice sites from a subset of proto-splice sites and also drove the evolution of a more efficient splicing machinery.
(2) The data suggest that proinsulin, normally processed in secretory granules and released via the regulated pathway, may also be processed, albeit less efficiently, by the constitutive pathway conversion machinery.
