Scientists discovered that this enhancer associated with hair color has a binding site for a particular transcription factor. one form of the binding site has the sequence cactaaag and is associated with dark hair, and the other form of the binding site has the nearly identical sequence cgctaag and is associated with blond hair. how could these two nearly identical enhancer binding sites lead to different rates of initiating transcription of the regulated gene?
