Molecular Genetics of Prokaryotes Problem Set

Problem 2: The role of the inducer of the lac operon

The inducer:

A. combines with a repressor and prevents it from binding to the promoter.

B. combines with a repressor and prevents it from binding to the operator.

C. binds to the promoter and prevents the repressor from binding to the operator.

D. binds to the operator and prevents the repressor from binding at this site.

E. binds to the termination codons and allows protein synthesis to continue.
