Computation doesn't care about mathematics. We can build physical computational machines which are nothing more than vast collections of fermions interacting with one another according to emergent principles which are merely consequential and can be explained according to the anthropic principle. The fermionic particles composing the computer have no knowledge of mathematics. The Universe doesn't care about mathematics.
Knot Theory isn't what binds DNA. That is insanity. Knot Theory models how DNA binding works in terms that humans can understand it and make valid predictions concerning it, but it doesn't explain the "hows" or "whys" of DNA. To explain the "how," you must look at how the underlying molecules that compose DNA interact with one another, and the underlying subatomic particles that compose the atoms and so on. The fact that DNA binds the way it does is an emergent consequence. The Anthropic Principle explains the "why."
Mathematics itself is emergent.
