Biologists have been messing with the console since a long time ago. They figured out what each gene does in large part by turning them off one by one, or occasionally making them run more than they should (overexpression). Even before they had the whole genome, they used random mutagenesis and slowly analyzed what got broken by breeding experiments. With enough data you can even locate it on a chromosome relative to known genes by linkage maps.
The most fun stuff to mess with is of course parts that controls how other stuff works. Figuring out what makes stem cells want to grow into shapes will lead us to more of these control switches.
