It Is Possible for a Repressor to Negatively Regulate the Expression

question 10

Multiple Choice

It is possible for a repressor to negatively regulate the expression of an operon because:

• A) the repressor induces the expression of the inducer by binding to the promoter that comes before the inducer gene.
• B) one of the structural genes expressed in the operon negatively regulates the repressor.
• C) the repressor-binding site overlaps the promoter site of the operon, allowing it to physically block the binding of RNA polymerase.
• D) the repressor-binding site on the DNA overlaps with the translation start site, thereby preventing the transcription.
• E) the repressor physically blocks where the activator should be binding on the operator region.
