You have a wonderful way of meandering around a question.<quoted text>
When two physical things interact, it is possible that the detailed properties of the two things are changed. The change is information about that interaction. That is what information *is*: a physical property that is different from some 'standard' in a way that is different because of an interaction with something else.
Information is common: a penny on the groun is information that there is a society able to make coins, mine copper, and that there was a method of conveyance to the site of that penny. A log in a forest has information about the tree, the environment of that forest, the atmosphere, etc.
The term 'coded information' is also a misnomer: ALL information is coded. It is 'coded' in the properties that reflect the interaction.
Now,'natural' codes like the DNA-protein 'code' are quite different than human designed codes. Human codes are made to convey abstract information that has no actual bearing on the precise physical structures carrying the information: whether we use graphite on paper, magnetic fields on a hard-drive, or pixels on a screen. Natural codes, on the other hand, are directly related to the physical processes they 'encode': protein density affects the rates of certain reations, that affects how much DNA is transcribed, etc. The loop is much, much smaller in natural systems than in human systems. It is also not 'abstract' information: the information has direct ties to the immediate physical situation.
You need to go learn what information actually is and how it is made and used.
I'll stick with the explanation provided by Norbert Weiner, father of cybernetics. He has a tad more credibility.
