How can a three-base codon evolve from a two-base codon? Inspired by this question among others. It's widely suggested that the current 3-base codon system of encoding protein sequences in DNA evolved from an earlier...
Its also likely that between 2 and 3 base codes a 2 base pyrimidine/purine system was used. Today the third base can often be switched for its pyrimidine/purine pair without changing the resulting amino acid.

A cell-permeable pyrimidine compound that potently induces the differentiation of ESCs (embryonic stem cells) into cardiomyocytes (EC 50 = 100 nM) without significant cytotoxic effect even at concentrations as high as 25 µM. The induction of cardiomyogenesis by Cardiogenol C is much more efficient than that achieved by EBs (embryoid bodies) formation and DMSO treatment.
