>> venter: no. we designed this just to see if we could do this whole experiment using synthetic d.n.a. and now that we know we can do it, it's worth the effort to now make the things that could be valuable. >> kroft: just how valuable remains to be seen, but venter believes this is the first baby step in a biological revolution, one in which it will be possible to custom-design and reprogram bacteria and other organisms to churn out new medicines, foods, and clean sources of energy. what you're doing is programming cells like somebody would program software. >> venter: d.n.a. is the software of life. there's no question about it. and the key to evolution of life on this planet, and now the key to the future of life on this planet, is understanding how to write that software. >> kroft: so, you see bio- engineered fuel, for example? >> venter: i see, in the future, bio-engineered almost everything you can imagine that we use. >> kroft: how far off is some of this? >> venter: the first things will sta
