7. to accomplish regulation in prokaryotes, operons (segments of dna) include specialized regions where a variety of regulatory proteins bind and detach to either initiate or inhibit transcription of the genes on that segment. (a) identify two of the proteins involved in the gene regulation in prokaryotes and their function. (b) describe the properties of the repressor that demonstrate it to be a protein. (c) discuss the evidence that proves it to be a repressor within the operon. (d) compare and contrast the roles of a repressor in an inducible system vs. its role in a repressible system.
