Check out this great article about synthetic biology past, present and future.
From this article:
"Many of us thought that working at the single-gene level was just a starting point, that we really needed to figure out how all these newly identified genes arising from the Human Genome Project fit into networks, pathways, and circuits inside the cell." —James Collins
"It struck me that probably something useful in evolution helped tailor properties in these compounds that made them better suited to work in complex cell systems like the human body." —Gregory Verdine
"The cost of both decoding DNA and synthesizing new DNA strands, he has calculated, is falling about five times as fast as computing power is increasing under Moore's Law, which has accurately predicted that chip performance will double roughly every two years. Those involved in synthetic biology, who often favor computer analogies, might say it's becoming exponentially easier to read from, and write into, the source code of life. These underlying technology trends, says Church, are leading to an explosion in experimentation of a sort that would have been inconceivable only a few years ago."
