Unformatted text preview: RNAmolecules that are not translated into protein. RNA Polymeras Binding and Initiation of Transcription The promoter of a gene includes within it the transcription starting point the nucleotide where RNA synthesis actually begins and typically extends several dozen nucleotide pairs upstream from the start point. The promoter serves as a binding site for RNA polymerase and determines where transcription starts, but it also determines which of the two strands of the DNA helix is used as the template. In bacteria, the RNA polymerase itself specifically recognizes and binds to the promoter, in eukaryotes, a collection of transcription factors mediate the binding of RNA polymerase and the initation of transcription....
