Didn't Shannon say that his information theory should not be applied to biology, genetics, life or something like that ?

Yeah, I'm checking that one out ... wasn't sure at the time I wrote that question, even less now since I can't seem to track the source down.
I'll keep looking, but I may have to retrack that question

One thing I am sure is that your initial definition of information in the context of genetics didn't include the semantic aspect.

Semantics is 'irrelevant to the engineering problem', this is different from 'irrelevant to information theory'.

Semantics is not part of Shannon's definition of information, since he was more concerned in transmitting information in a wire then to develop the full idea what is information etc.
Nonetheless, semantics is part of information. I mean, if information was one dimensional as Shannon proposed, then 'I have a black dog' would have less information then ''J'ai un chien noir''. But in reality, these two sentences have the same amount of information for the receiver.

Ok then we agree
BTW I never found that quote where Shannon talks of biological systems. So unless I ever find it in the future, it doesn't exist and I agree I was in error.
