    The Nucleotide and Nucleotide-Like Coenzymes in Primitive Metabolism, Photobiology and Evolution

    The evolutionary link between hypothetical primordial RNA world [1] and the modern R(D)NA/Protein biosphere can hardly be revealed by only searching for chemical roots of primitive genetic coding. The analysis of...
