Sorry, the cite you posted admits in it’s first paragraph…
Other than the fact it is not a belief, it is a conclusion reached by examining the evidence, I agree that this is the view of main stream biologists. Your cite then goes into a desperate attempt to attach information TO THE DNA MOLECULE, calling it semiotics. This is pseudoscientific non-sense. Again the map is not the territory, there is no information or code in the DNA molecule, the information or code is added by those studying DNA for their own benefit or understanding, the DNA has no ability to interpret code, it does not contain information, it needs no interpretation to do what it does strictly according to it’s chemical properties according to the laws of physics. Again, the Hydrogen atom contains no information telling it how to form water, that is no different for the DNA molecule, it is a template that directly, physically assembles molecules that perform the functions of life. The information and code is completely contained in the maps we make(so that WE can interpret and understand what the DNA molecule does), but it is not in the territory itself(the DNA molecule).
Do you think there is information or code contained in the contours of a patch of ground? We can develop information by measuring that patch, turn those measures into a map of that patch, but the patch itself contains no information. So when it rains we may know the exact shape, depth and outline of the puddle that will form on that small patch down to the smallest detail, but the patch of ground knows nothing of all this information, nor does it need to, it will form the puddle to those exact dimensions based simply on the laws of physics. You are still mistaking the map(information, code, etc.)for the territory.
