Suppose an experimenter becomes proficient with a technique that allows her to move DNA sequences within a prokaryotic genome.If she moves the regulatory gene (lac I),along with its promoter,to a position some several thousand base pairs away from its normal position,which would you expect to occur?
A)The repressor will no longer be made.
B)The repressor will no longer bind to the operator.
C)The repressor will no longer bind to the inducer.
D)The lac operon will function normally.

The lac operon is designed to function with its components spread out across the genome. Moving the lacI gene and its promoter does not inherently disrupt the production or function of the repressor protein; it can still be made, bind to the operator, and interact with the inducer as long as the regulatory sequences necessary for its expression and function are intact and accessible.
