And yet the paper tape of a plant or animal genome (as opposed to a virus) also contains the instructions for the OS and the bio-replicator, which is part of what's so fascinating about it.
I don't think that's accurate at all. The DNA has no effect on the cellular soup - the RNA etc - that are the bioreactor. That you got from some ancestral Eve. It changes perhaps over time, like anything else through random chance. But its independent of the DNA, which is a tiny part of the whole.
