Insight into the mechanism of nonenzymatic RNA primer extension from the structure of an RNA-GpppG complex

The nonenzymatic copying of RNA templates with imidazole-activated nucleotides is a well-studied model for the emergence of RNA self-replication during the origin of life. We have recently discovered that this reaction can proceed through the formation of an imidazolium-bridged dinucleotide intermed...
