Q. When tryptophan accumulates in a bacterial cell





... Answer is C). it binds to the repressor, causing it to bind to the operon

Explanation :

If free tryptophan accumulates within a bacterial cell, it binds to the allosteric site in the Tryptophan repressor, inducing a conformational charge that permits the tryptophan repressor complex to bind to at least three 21-bp operator sites.
