A promoter site is a region of DNA that RNA polymerase binds to in order to carry out transcription. It is located upstream of the target sequence [1]. A promoter sequence determines where transcription of a gene will begin and also dictates the efficiency with which transcription takes place - cells use the degree of efficiency regulate the amount of a particular protein produced.
