I trained initially as a physical chemist, and then, after becoming interested in biology, I went to medical school and learned how to be a physician. So, I'm a physician scientist.

I think history would say that medical research has, throughout many changes of parties, remained as one of the shining lights of bipartisan agreement, that people are concerned about health for themselves, for their families, for their constituents.

The human genome will not help us to understand the spiritual side of humankind, or to know who God is or what love is. The well-heeled couple who decide they want to use genetics to have a child that is a gifted musician may end up with a sullen adolescent who smokes marijuana and doesn't talk to them.

The problem [with genetic research] is, we're just starting down this path, feeling our way in the dark. We have a small lantern in the form of a gene, but the lantern doesn't penetrate more than a couple of hundred feet. We don't know whether we're going to encounter chasms, rock walls or mountain ranges along the way. We don't even know how long the path is.

[Decoding the human genome sequence] is the most significant undertaking that we have mounted so far in an organized way in all of science. I believe that reading our blueprints, cataloguing our own instruction book, will be judged by history as more significant than even splitting the atom or going to the moon.

Scientists must venture outside their comfort zones to show the public how cool - and how important - their work really is.

But full sequencing? No. Very hard to interpret. At some point probably we'll all have that opportunity but most of what's there will be stuff that we don't know what to say much about. So it's a great research tool, but for clinical purposes to advise somebody to practice better health maintenance, it's not necessarily gonna be a big one for a while.
