Chapter 18, Problem 6

What would occur if the repressor of an inducible operon were mutated so it could not bind the operator? a. irreversible binding of the repressor to the promoter b. reduced transcription of the operon's genes c. buildup of a substrate for the pathway controlled by the operon d. continuous transcription of the operon's genes

Video transcript

Hi everyone here we have a question saying continuous transcription of the aprons gene will take place. A If repressor of an induce A Ble operation is mutated. This is incorrect be if the repressor cannot bind to the operator. If the repressor cannot bind to the operator, it will cause continuous transcription. However, this answer is not complete. See by reversible binding of the repressor to the mote promoter. This is incorrect. D. If the repressor is mutated and cannot bind to the operator, this is correct. If the repressor is mutated, the operator cannot bind and it will cause continuous transcription of the operations gene. So our correct answer is D. If the repressor is mutated and cannot bind to the operator. Thank you for watching. Bye.
