Question

5. The clog operon produces enzymes that convert compound A into compound B. The operon is controlled by a regulatory gene S. Normally, the enzymes are synthesized only in the presence of a third compound C. For all mutations of the S gene identified, the enzymes are not synthesized in the presence or absence of compound C. a) Is this operon inducible or repressible? Explain your answer. b) Does gene S produce a repressor or an activator? Explain your answer.

Step 1

Step 1: The clog operon is inducible because the enzymes are only synthesized in the presence of compound C, indicating that the operon is turned on or induced by the presence of this compound. Show more…
