Question

Quizplus · Accepted Answer

The indcuer is a molecule that binds to a repressor protein and interacts with it in such a way that it changes its shape and becomes unable to bind to the operator region. As a result, RNA polymerase can access the promoter region and initiate transcription of the genes that are part of the operon. The operon is a functional unit of DNA that includes structural genes, an operator region, and a promoter. The repressor is a regulatory protein that can bind to the operator, prevent RNA polymerase from accessing the promoter, and decrease the rate of transcription. The corepressor is a molecule that binds to a repressor and activates it, thereby increasing its affinity for the operator and decreasing the rate of transcription.
