transcription factors
... Genes are transcribed (copied) into 'messenger RNA' by an enzyme called RNA Polymerase [RNAP]. Polymerase binds to a 'promoter region' at the beginning of a gene. The polymerase traverses the gene, copying as it goes. Polymerase normally leaves DNA at the gene's end. Multiple polymerases may be ...
