Ringo,
I don’t mean to put a hoot in an owl’s beak, but, Hoot is essentially correct in his “language” analogy. DNA is a code. There is no better way to describe the function of DNA than as a code. Keep in mind that Hoot (and he should correct me if I am wrong) is building a metaphor to describe what is happening. The DNA as a code is especially apt and describing the code as a language is not beyond reason.
We use symbols (A,G,C,T and sometime U) to represent the nucleic acids in the gene and the RNA. Every triplet of nucleotides is akin to a “word.” The word is a code for a specific amino acid and the “syntax” of this “language,” its sentence structure, codes for a specific protein to be built.
The science of “information theory” likes to treat such systems akin to computer codes and DNA fits information theory quite well as an analogous computer language.
I, as I suspect you, have been awaiting Hoot to drop the other shoe and expand the analogy to justify some metaphysical underpinnings to the “code,” “language,” “digital instruction” whatever. He hasn’t crossed that line, yet, and I am willing to agree with Hoot that the analogy of DNA as code, codon as language, is, as restricted to analogy, quite appropriate.
Let’s see where he goes with this.
