Regarding the three stop codons as identical function is like considering two of the three codons to be 'junk'.
Nice try to weasel out. "Junk DNA" is a term with fixed meaning. Also, regarding the three stop codons as being functionally identical means to mean two of them to be redundant, not "junk" (which two of the three would be the junk?). Given the similarity of the three stop codons, I'd guess the redundancy provides some protection against mutations.
I disproved the notion that 'synonymous' codons were interchangeable, in 1990, just about the time 'bioinformatics' was being coined. What I disproved was the basis for Anfinsen's Nobel Prize.
The work you did in 1990 was the basis for Anfinsen's Nobel Prize in 1972? Yeah, sure. I guess you also invented the time machine?
But nice try.
Also, if you were working in the field, you'd for sure know what "junk DNA" means.
