Most repressor proteins are allosteric. Which of the following binds with the repressor to alter its conformation?
A) inducer
B) promoter
C) RNA polymerase
D) transcription factor
E) cAMP

Question

Inducer molecules bind to repressor proteins and cause a conformational change that prevents the repressor from binding to the operator region. This allows RNA polymerase to bind to the promoter and initiate transcription of the gene.
