Question

Assume that a deletion mutation occurs within the trp operon so that the DNA corresponding to the last (distal) part of region 1 and the first (proximal) part of region 2 of the mRNA 5′ UTR is removed. What will be the effect of this deletion on the expression of the trp structural genes?

Answer 1

Hopefully this helps! If it doesn't, let evil.

Step-by-step explanation:

In the absence of tryptophan, transcription of the structural genes will be reduced compared to a wild-type operon.
