Your friend has discovered that the same human promoter is responsible for producing two different proteins. In Kidney cells it is responsible for the production of protein A while in Brain cells it is responsible for the production of Protein B.  Your friend has concluded that this promoter must be controlling two different genes. Do you agree or disagree with your friend's conclusion? Explain why or why not. Be sure to describe the molecular events to support your answer.
