Abstract.
A better definition of the structural and thermodynamic determinants of the interaction of nucleic acids with proteins is shedding light on the origin of the genetic code, protein synthesis, and nucleic acid replication. This is also allowing to show a consistent biochemical framework for the appearance of these fundamental synthetic mechanisms. This article reviews recent significant developments in the field, and discusses an integrated model for a biochemically plausible evolution of these fundamental mechanisms of synthesis. This model is based on sequence-specific interactions between abiotically synthesized polynucleotides and polypeptides, and can account for a coordinate evolution of the genetic code, protein synthesis, and nucleic acid replication in living cells.
