If in an experiment you mutate the two trp codons in the attenuator to ala codon what will be the impact on repression? Correct Answer Reduced repression
The basis of attenuation at the attenuator is the presence of two trp operon which stalls the RNA polymerase when trp is deficient. Mutating the trp to ala eliminates the attenuator’s mode of repression. However, there is still an intrinsic mode of repression by binding of a repressor, which is still active.
