Could somebody give me an idea of what we can and can't do with genetic engineering? (Im not talking about altering existing beings, I'm talking about how we can create new beings)
The problem is - a lot of stuff is unknown. Before one tries to build it, its usually wise to understand fully how it works. That is where system biology comes in - trying to fit everything into a model. Dont forget that we've only discovered DNA 50 years ago, and computers are only now beginning to be relatively powerful enough to do that sort of research.
