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?

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

Explanation:

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

the circled areas are referred to   as sunspots.   the sunspots are cooler than the   surrounding area.

sunspots are temporary phenomena on the photosphere of the sun that appear visibly as dark spots compared to surrounding regions. they correspond to concentrations of magnetic field flux that inhibit convection and result in reduced surface temperature compared to the surrounding photosphere.

what are the options
