"I wouldn't call DNA source code either." Well here's the thing. You are completely right. DNA interacts with its surroundings. It forks, splits, mutates. It is not at all like static source code. However, if you take the software analogy to the limits of our current understanding, you might be able to model it as polymorphic code that is also a quine that runs in a massively multithreaded, multiprocessor environment. Good luck using that analogy for anything useful.
