摘要

It is well established that the evolution of life passed through an early stage in which RNA played central roles in both inheritance and catalysis - roles that are currently played by DNA and protein enzymes, respectively. But where did the RNA come from?rnExperiments reported by Powner et al. (page 239 of this issue) provide fresh insight into the chemical processes that "might have led to the emergence of information-coding nucleic acids on early Earth.
