Match the following mRNA sequence to its nontemplate strand DNA sequence.   5′-AUGCGGUUGCAG-3′

In this figure, are the RNA Polymerases moving from left-to-right or from right-to left?   

The figure below shows the promoter region for a prokaryotic gene, with the binding sites for RNA polymerase in blue and green.  You create a mutant in this promoter by inserting 7 nucleotides (+7-bp) just upstream of the -1 position.  In a few sentences explain what effect this 7-bp insertion in this location would have on (1) the rate of transcription rate, (2) the position of the transcription start site, and (3) the sequence of the RNA transcript. (2 pts.)
