VC, tell me a symbol system that is not material/chemical/follows inexorable law.
Name one.

VC,
When you touch something warm, do you then have "warmth" going through your nerves to your brain?
Of course not, you have a neural representation of warmth.
And does anyone actually believe this neural representation can be isolated and "warmth" be measured from it??
Of course not, it is a representation that must be recognized and interpreted (at the sensory cortex) just like any other representation.
Again you are trying to blur the line here
NO…I’m not. I’m trying to get you to understand the fundamental fact that ALL information acts under the same inexorable physical laws. You do not get a special exception for DNA.
DNA, as a medium of information, has to be translated under the same inexorable physical laws as any other medium of information.
The method of that translation is settled science, it is not even controversial.
You are (probably unknowingly) DENYING physical reality, and I am trying to draw your attention to that fact.
If you want to vent your spleen against religion... well then knock yourself out .... BUT you do not get to deny reality and then pretend that your rant against religion is powered by physical evidence, because that is an out and out lie.
I think its pretty clear to everyone here that you are just trying to twist things to inject your "intelligent design" rubbish.

It might work on people like tink and your church group that are really looking for anything that justifies their belief, but the thin veil of "science speak" and silly analogies won't work on most here.
I don't really get anything stimulating out of the discussion with you, so don't mind me if I end up ignoring your posts
VC,
When you see a sign painted in red with the pattern “STOP” on it, do you think that this paint and those shapes chemically represents “Apply your brakes”?
Of course not. It has to be interpreted in a system.
.
When an ant passes an ALERT pheromone to the other ants causing them to defend their mound, do you think that the pheromone chemically represents “SAVE THE QUEEN!”?
You just want to think otherwise of DNA.
They must be interpreted in a system.
The manner of that system is entirely understood. Its not even controversial.
You just deny it
A lifelong atheist (not that it matters), a physicist, a professor emeritus, a thoughtful intellect -- a man who studies symbol systems for 50 years, becoming a most-revered expert on the subject, writes dozens of papers telling you that you are just completely and utterly wrong wrong wrong, and you refuse to even consider it. You do so because it doesn't fit well with your metaphysics, and for no other reason.
Man of science and reason.....yeah sure.
exactly, a stop sign is an example of a true symbol.
The Basics
In all living things, proteins are the workhorses inside the cell. They build structures, regulate processes, transport materials, and take part in virtually every function of cellular life. Well over 100,000 different types of proteins have been found in the living kingdom, and each of them is created by using just 20 different types of amino acids arranged as building blocks in a particular order. Changing the order of the amino acids changes the type of protein being created, and while an average protein might be made up of 200-400 amino acids, others have thousands. Living cells know how to arrange the order of these amino acids by reading the information encoded in their DNA.
In order to encode this information, four different types of nucleic acids (adenine, thymine, guanine, and cytosine – A,T,G,C) are used to form individual representations called “codons”. A codon can be thought of as a "code word" inside the cell. Each of these code words is made up of three nucleic acids (triplets) which are read together as a single representation. For instance, the triplet TAC is translated by the cell to add an amino acid called tyrosine to a new protein being created. CTA means add leucine, GTC means add valine, CCG means add proline, GAC means add aspartic acid, and so on. This is how the cell builds every protein in the living world - it uses a code.
The Input of Information
When the cell manufactures a new protein, it starts the process by locating the correct segment of its DNA for building that particular protein. The sequence of codons in that segment are then copied into a secondary mobile medium called "messenger" RNA (mRNA). When the information is copied into RNA, the nucleic acid thymine is substituted with another nucleic acid called uracil, but the pattern of the codons remains the same. This RNA copy is then matured and transported to the site of protein assembly, which is a molecular structure called a ribosome. Upon entering the ribosome, the sequence of codons in the messenger RNA are used to arrange the order of another set of RNA molecules called "transfer" RNA. These tRNA carry with them the individual amino acids that will be used to build the protein.
In short, the information in DNA is first copied into mRNA, and the mRNA is then used to order tRNA (with their amino acids in tow) in the same sequence as it existed in the original DNA. After all the amino acids are bound together in the right sequence, the chain of amino acids is then folded up into the protein that the cell needs to survive.
The Point of Translation
The input of information into the ribosome results in amino acids being attached together in a sequence prescribed by the DNA. Each critical step in this process is controlled by purely mechanical (deterministic) forces. However, in order for the genetic system to translate the form of a protein through the medium of nucleotides, the system cannot rely on deterministic forces alone to achieve that result.
To achieve translation, a set of arbitrary relationships must be established in the operation of the system, and these relationships can only exist if the various codons are mapped to their amino acids while the discontinuity (i.e. the arbitrariness) between them is preserved. This requires the system to be organized in a specific way to bring those relationships into being. Inside the cell, this organization is accomplished by isolating the establishment of the code from the translation of the codons.
In the genetic translation system, the relationships that make up the genetic code are established by a very special set of twenty complex proteins called aminoacyl tRNA synthetase (aaRS). The aaRS are the physical protocols in the genetic translation system. It is their job to load the correct amino acids to each of the tRNAs, and they accomplish this task prior to the tRNA ever entering the ribosome. Therefore the establishment of the genetic code is both spatially and temporally isolated from the remaining translation process. One process (the input of form) is functionally coordinated with the other process (the establishment of an effect) yet the two processes remain independent. The contingent organization of the system thereby establishes the genetic code while maintaining the discontinuity that is vital to its function.
Summary
A living cell is a heterogeneous system. It requires discrete parts in order to function, and reproduces itself by means of prescriptive synthesis. This process requires the translation of an informational medium. The minimum requirements for the origin of the system are therefore established by what is physically necessary to record and translate the amount of information that the system needs to successfully describe itself into memory.
A physical analysis of the system makes explicit what those requirements are.
The necessary material conditions of genetic translation are found to be exclusively identifiable among all other physical systems. They can be identified nowhere else in the physical world except in recorded language and mathematics – two universal correlates of intelligence.

VC,
By the way, since you see DNA translation as nothing but chemistry, you may be wondering how is it possible for the nucleic acids in DNA to not physically determine which amino acids are being added to the proteins being built, after all, that’s the whole point -- the cell reads the DNA in order to know how to build itself, right?

Biosemiosis,
Are you asserting that DNA contains messages from God ?
(Yes or no please).
If so , what do you think these messages say ?
