 We are now going to look at ways that genetics can be used to study gene regulation. Up to this point, we have examined gene function as something static and unchanging. But many prokaryotic and eukaryotic genes change their activity depending on the environment cells find themselves in. The question we wish to ask is: how do cells adjust the expression of genes in response to different environmental conditions?  We are now going to look at ways that genetics can be used to study gene regulation.
