" Synthetic biology56 is built around the idea that DNA is essentially software—nothing more than a four-letter code arranged in a specific order. Much like with computers, the code drives the machine. In biology, the order of the code governs the cell’s manufacturing processes, instructing it to make specific proteins and such. But, as with all software, DNA can be reprogrammed. Nature’s original code can be swapped out for new, human-written code. We can co-opt the machinery of life, telling it to produce—well, whatever we can think of. "
