Question

If a frameshift mutation occurs in the luxR gene of A. fischeri, which of the following would occur?

A. blockage of diffusion of the autoinducer into the cell

B. translation of the full luxR gene

C. translation of a normal functioning luxR protein

D. no activation of the lux operon

I can eliminate choice A but I think that's the only right answer. So can anybody help? And please explain a little bit. Thanks!

Due to frameshift mutation in a gene encoding Lux R, there will be a syntheis of a different protein. So the function of Lux R will be imoaired.

The option D seems to be the correct option.
