RESUMO
The proposal that RNA preceded DNA in evolution is more than 15 years old. In light of recent studies on RNA processing (including protein-free reactions), present knowledge about eukaryotic gene structure, and studies comparing ribosomal RNA sequences, we propose a train of events for precellular and early cellular evolution.
