Both genes should have have enhancers.
Enhancers are sequences of DNA and the DNA is the same in all cells.
What changes is not the enhancers but the transcription factors that bind to them. The enhancers are different from each other and bind different sets of transcription factors. Enhancers can be far away from the genes they control and can be either upstream or downstream from the start of transcription. The DNA in the hypersensitive site should be more sensitive than DNA in nucleosomes but less sensitive than naked DNA, which has no protein at all to protect it. Q should have more than one cytoplasmic domain, since G proteins are usually 7 pass proteins.
