... b) Mutant 1 has a loss-of function mutation in which component of the operon? Explain. Mutant 1 has lost the function of the operator, O, such that repressor cannot bind. Operators act at the level of DNA and can only control the genes to which they are physically attached. Even when a wild type cop ...
