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..

The energy of a wave depends upon its frequency. The greater the frequency of the wave, the greater is the energy possessed by it. As the audio signal frequencies are small, these cannot be transmitted over large distances if radiated directly into space. The only practical solution is to modulate..
