Post by: dracko on Nov 15, 2017 Imagine that you discover a bacterial operon involved in the synthesis of vitamin B12. This operon is regulated by a repressor protein that binds to an operator sequence. Vitamin B12 is the allosteric effector of the repressor—the molecule that binds to the repressor to affect its activity. Predict how vitamin B12 will influence repressor activity.
A) When vitamin B12 binds to the repressor, the repressor binds to the operator. B) When vitamin B12 binds to the repressor, the repressor cannot bind to the operator. C) When vitamin B12 binds to the repressor, the repressor can bind to RNA polymerase. D) When vitamin B12 binds to the repressor, the repressor cannot bind to RNA polymerase.
