You are studying a new gene that is expressed within the adipose tissue of humans during the development of diabetes. Specifically, you want to learn why gene expression levels are very high in those people who develop diabetes. What DNA sequence would you concentrate on? Group of answer choices A specific response elements B the TATA box C enhancer sequences D promoter proximal elements E metal response elements
