The DNA nucleotide sequence to which RNA polymerase binds to initiate transcription is called the:

The region of the DNA to which the polymerase binds to initiate transcription is recognized as the promoter. Most promoters extend over a sixty base pair area of the DNA sequence. The nucleotide sequences of many promoters have been identified, but there appears to be little conservation of sequence among them. Ref: Weil P. (2011). Chapter 36.
