Doctors may be able to inject a functioning copy of the gene mutated in Sam's DNA in the cells of his eyes. If the procedure were successful, would you expect Sam to regain his vision? Why or why not?

Yes.

Explanation:

Yes, Sam regain his vision and seen clearly because the injected gene go to the site where the damaged cell is present which is responsible for vision is replaced by injecting functioning copy of the gene and starts working and the person can see clearly. First the functioning copy of the gene is mutated with Sam's DNA in the cells of his eyes in order to adjust with the gene of eye and then injected so the Sam's DNA can accept the newly mutated gene.
