What is the likely effect of each of the following mutations of the trpLregion on attenuation control of trp operon gene transcription? Explain your reasoning.

a. Region 3 is deleted.

b. Region 4 is deleted.

c. The entire trpL region is deleted.

d. The start (AUG) codon of the trpL polypeptide is deleted.

e. Two nucleotides are inserted into the trpLregion immediately after the polypeptide stop codon.

f. Twenty nucleotides are inserted into the trpLregion immediately after the polypeptide stop codon.

g. Ten nucleotides are inserted between regions 2 and 3 of trpL .

h. Two nucleotides are inserted immediately following the polypeptide start codon

i. The entire polypeptide coding sequence of trpLis deleted.

j. The eight uracil nucleotides immediately following region 4 are deleted.

There is Hyaluronic acid synthesis occuring in Group X Strep and it is controlled by an operon with 3 genes, called hasXYZ. Based on the 3-line diagram model,  a. How many ribosome binding sites are there for the protein? b. How many promoters are there for the genes? c. How many start codons are there for the protein? d. How many RNA Polymerase binding locations are there for the genes? e. How many proteins will be fully functional? f. How many mRNA strands are made?
2) Attenuation of the trp operon is controlled by the formation of stem-loop structures in the mRNA of the trpl region. The attenuation function can be disrupted by mutations that alter the sequence of the repeat DNA regions 1-4 and prevent formation of the RNA stem loops. Describe the most likely effects on attenuation of each of the following mutation under the conditions specified. a. Mutation in region 1 and low levels of tryptophan: b. Mutation in region 2 and low levels of tryptophan: Mutation in region 2 and moderate levels of tryptophan (low enough to release the repression but enough to allow the ribosome to NOT pause): с. d. Mutation in region 3 and low levels of tryptophan: е. Mutation in region 3 and moderate levels of tryptophan (low enough to release the repression but enough to allow the ribosome to NOT pause): f. Mutation in region 4 and low levels of tryptophan:
a. The original constitutive operator mutations in thelac operon were all base changes in o1. Why doyou think mutations in o2 or o3 were not isolated inthese screens?b. Explain how a mutagen that causes small insertions could produce an ocmutation.c. Would a strain with one of the ocmutations described in part (b) and also a lacIS mutation be ableto make β-galactosidase either in the presence orabsence of inducer? Explain
