title: Omnipotent RNA.
abstract: The capability of polyribonucleotide chains to form unique, compactly folded structures is considered the basis for diverse non-genetic functions of RNA, including the function of recognition of various ligands and the catalytic function. Together with well-known genetic functions of RNA - coding and complementary replication - this has led to the concept of the functional omnipotence of RNA and the hypothesis that an ancient RNA world supposedly preceded the contemporary DNA-RNA-protein life. It is proposed that the Woese universal precursor in the ancient RNA world could be a cell-free community of mixed RNA colonies growing and multiplying on solid surfaces.
