You discover a strain of mouse which has a mutation in the Opsin binding domain of the Transducin gene. This mutation causes the Transducin protein to be unable to bind the Opsin protein. What about the phototransduction pathway in these mice is true? A. Transducin will not activate phosphodiesterase. B. Opsin will not bind cis-retinal. C. Photochemistry will not take place. D. The plasma membrane will become hyperpolarized.
