This analogy is workable, but I would make some changes. For example, epigenetics don’t change file.c, but how readily the rest of the process interacts with it

This analogy is workable, but I would make some changes. For example, epigenetics don’t change file.c, but how readily the rest of the process interacts with it. The ribosome produces file, but isn’t the file itself, whereas in some of your other entries the bio part is analogous to the computer part.
