In the E. coli trp operon, what would be the effect ofa deletion in the region 2 sequence, which would prevent it fromforming stable RNA hairpin structure with either regions 1 or3?
A) The Trp repressor could not bind to the operator andtrp transcription will be high, even in the presence ofhigh tryptophan concentration.
B) Translation of the leader sequence could not be initiated.
C) No effect on trp operon transcription.
D) Transcription of the trp operon could not beinitiated.
E) Hairpin 3:4 would form even when tryptophan is low, and thiswould constitutively attenuate transcription of the Trpoperon.
