answer:I think that you are over anthropomorphizing DNA. It is just a chemical. It doesn’t ‘know’ anything. People are not just DNA. If you wanted to base your analysis of what a person is purely on chemistry it would be better to say that people are just water rather than DNA. DNA is used to hold the ‘plans’ for building other chemicals that form part of the complex matrix that makes up a living organism (not just people). Just like the plans for a building is not the real building, DNA is not the organism. I don’t think anything else on Earth but people know about pi, so I would think that human DNA has no better understanding of pi than the DNA of a worm.
