A) pancreas and muscle cells have the genes for both insulin and myosin active.
B) the active gene in pancreas cells is the one for insulin,while the muscle cells have genes for insulin and myosin.
C) pPancreas cells activate the gene that would produce insulin,while muscle cells activate the gene that would produce myosin.
D) neither pancreas cells nor muscle cells are specialized.
E) only muscle cells can produce proteins.
