operates cable systems

A coaxial cable consists of an inner conductor and an outer conductor, separated by a dielectric insulating material. The inner conductor is made of a copper wire encased inside the dielectric material. As for the outer conductor, it is made of copper, tinned copper, or copper-coated ste..

This gene controls a specific series of structural genes, and lies adjacent to them. It remains turned on because it is not bound by the repressor protein produced by the regulator gene. Therefore, the cistrons keep functioning, producing enzymes. The latter catalyse the synthesis of tryptophan fro..
