Genetic regulation in prokaryotes can involve alterations in rna secondary structure. what phenomenon occurs in the trp operon that involves such alterations?

The phenomenon that occurs in the trp operon which involves such alterations is Attenuation. Trp operon is a group of genes that are used or transcribed together and codes for the components for the production of tryptophan. This phenomenon of attenuation is a mechanism for reducing expression of the trp operon when levels of tryptophan are high. However, rather than blocking initiation of transcription, attenuation prevents completion of transcription.
