With biology the genes that express polypeptides do in a sense control things. Biology is not so much about control as it is about commensurate networks. We are in a time when aspects of the natural world are often compared to technology. For instance with Seth Lloyd we have the idea the universe is a computer. The universe has computational aspects to it, but it is not really a computer. If the universe is a computer then what is it computing? I think the same hold for biology, where we like to make comparisons between biological and molecular biological systems with nanotechnology, but there are departures.
