I am not talking about RNA. I am talking strictly about. The way DNA stores information has nothing to do with the way it is folded. Proteins and some types of RNA require proper folding to function, DNA does not.
Further, even a duplex is a "fold" (coiled coils are a structural motif).
You're fixating on the A T G C base form of encoding; DNA contains a lot more information than just that, encoded in its quatenary structure.
