- Could there be some kind of molecular editing system? What tools could be devised to work with genes?
- Could scientists then create tailored DNA molecules? In the early 1970s, researchers discovered naturally-occurring enzymes that could be used to tailor-make DNA molecules.
- The idea that DNA still "functions" when transferred from one organism to another opened up worlds of possibilities.
- Could biomedical scientists insert the DNA sequence for human insulin into bacteria, and let the bacteria be the factory to produce unlimited quantities of insulin?
