And what did University of Washington researchers mean when they use the word "code" in this 2013 research report?
quote:Since the genetic code was deciphered in the 1960s, scientists have assumed that it was used exclusively to write information about proteins. UW scientists were stunned to discover that genomes use the genetic code to write two separate languages. One describes how proteins are made, and the other instructs the cell on how genes are controlled. One language is written on top of the other, which is why the second language remained hidden for so long.
1 - I am a native English speaker. I understand these things.
2 - You have avoided every question asking you to explain your claim that there is a difference between the chemistry of DNA and chemistry that doesn't contain a code. That is internet code for "I'm not honest".
Actually my replies tend to be rather terse, and, as befits their target, couched in fairly simple language. Quite the opposite of word salad.
But it's kind of cute the way you mimic the grown-ups language. Sort of like a little boy standing in his daddy's shoes, a fedora covering half his head, pretending to shave with whipped cream and a toothbrush handle. So do please carry on.

You might try reading the WHOLE article...
Wise words. You might consider reading the abstract of the paper itself instead of just the PR fluff about the paper.
"Genomes contain both a genetic code specifying amino acids and a regulatory code specifying transcription factor (TF) recognition sequences. We used genomic deoxyribonuclease I footprinting to map nucleotide resolution TF occupancy across the human exome in 81 diverse cell types. We found that ~15% of human codons are dual-use codons (“duons”) that simultaneously specify both amino acids and TF recognition sites. Duons are highly conserved and have shaped protein evolution, and TF-imposed constraint appears to be a major driver of codon usage bias. Conversely, the regulatory code has been selectively depleted of TFs that recognize stop codons. More than 17% of single-nucleotide variants within duons directly alter TF binding. Pervasive dual encoding of amino acid and regulatory information appears to be a fundamental feature of genome evolution."
They seem to have left out the part about the "code" being designed.
