Ethical issues aside (which is essentially the biggest issue to be solved), I could see great value in applying some software methods to biology, among which something akin to unit testing. What would be needed is a way to reliably test drugs in conditions as close to in vivo as possible (if going full SF, we can imagine full warehouses of human bodies that would be bred, preferably without brains for those aforementioned ethical issues -- unless you are creating a dystopia universe -- for the purpose of testing drugs, and harvesting organs). I cannot imagine how big an impact it would have on healthcare, biology and more general human body-related issues. SF technologies like prosthetics, cryo-preservation/life support, stem cell regeneration, embryology and in vitro fetus development, cloning for "body parts", and countless others would suddenly seem a lot closer. I don't think that kind of thing will happen any time soon, though. It may happen in the future if alternative technologies can't replace it (simulation, nanoscale engineering). Such topics can quickly become extremely philosophical. I initially wrote a paragraph on what dying means to me (maybe fine with it), etc; on which I think I could go on for pages, but I think it would be better to stop here :)
