Most repressor proteins are allosteric. Which of the following molecules binds with the repressor to alter its conformation and therefore affect its function?
A) inducer
B) promoter
C) transcription factor
D) cAMP

Question

Quizplus · Accepted Answer

Inducer molecules bind with repressor proteins to alter their conformation and therefore affect their function. This results in the release of the repressor from the operator site, allowing RNA polymerase to initiate transcription. Promoter and transcription factor molecules do not directly interact with repressor proteins, while cAMP is involved in the regulation of gene expression by binding to activator proteins.
