Which RNA polymerase component is required for promoter recognition in prokaryotes?

How do many DNA binding proteins recognize specific DNA sequences?

RNA Polymerase was shown biochemically to bind tightly to the following 50 nucleotide piece of double-stranded DNA from the E. coli genome, indicating that it likely contains a basal prokaryotic promoter.  The -10 promoter recognition sequence is underlined. Star indicates the nucleotide pair that occurs at the +1 transcription start site. Given the double-stranded sequence below, answer the following questions:                        Please watch your spelling!    a) Based on your analysis of this promoter region, which strand, top or bottom, will be the template strand? Template will be [tmpl] strand   b) Based on your analysis of this promoter region, in which direction, left or right, will transcription proceed?Transcription will move to the [drc]   c) Write the first eight nucleotides that will make up the beginning of the mRNA made from this promoter:The first 8 nucleotides will be: 5’ [sequence]  

Which of the following is NOT a common DNA binding domain?
