Hello AdminNosy,
Coded information = a system of symbols used by an encoding / decoding mechanism that transmits a message which is seperate from the communication medium itself.
Examples would be english, computer languages, radio signal and music and yes, DNA. All known codes always involve a system of symbols which represent a idea, concept or plans etc.
As far as my view on this, I don't see how the laws of physics and chemistry alone can account for the coded information contained in DNA. All known codes that we know the origin of always come from intelligent activity.
The next question I suppose is will we all agree DNA contains coded information or not. I say it most surely does based on information theory itself. We can start here I guess, thx.
