The figure belоw shоws the prоmoter region (upper strаnd, 5' > 3') for а typicаl prokaryotic gene, with the binding sites for RNA polymerase in orange and green, the positions of the -1 and +1 nucleotides, and the position of the ATG START codon noted. You decide to test how mutations in this region affect transcription by inserting 12 additional nucleotides (5’-CGTCAACTGCAT-3’) at four different positions, using one 12-bp insertion for each mutation (A to D). For each of the four different insertional mutations (A though D) shown in the figure, explain in a few words, what the effect will be, if any, and why or why not, on (1) transcription initiation, (2) the position of the transcription start site, and (3) the sequence of the mRNA produced. I expect four answers with 3 parts each. Hint: In your answer, use the "+ down arrow" button to insert a table (4 columns x 5 rows), add the headers and mutation letters to answer the problem.
