Why did scientists edit the genes of bacteria to produce insulin?
Because the bacteria were diabetic
Because bacteria have simple DNA that is easier to manipulate, making it easy to produce insulin in a lab
Because bacteria's complex DNA was perfect for insulin production
Because insulin has no use outside of a lab setting
