Eddie, you can say this over and over, all you want. Your ill-informed assertions do not change the fact that you live in an RNA World. The raison d’être for protein and DNA is to make RNA, specifically to make ribosomal RNA. RNA sits at the center of the goings on in the cell - the most important catalysts, the most important regulators, the most important communicators, are all RNA, or they derive directly from primordial mechanisms that center on RNA.
