Regulation of Transcription
... • Essentially the molecule “RNA polymerase” must bind to an “exposed“ part of DNA strand called a promoter; it must then move, in the 5’ to 3’ direction, “transcribing” the DNA sequence of “the gene” to RNA. – The transcribed sequence begins at the Transcription start site (TSS) and finishes at the ...
