The RNA World hypothesis is the idea that RNA could have jumpstarted Earth’s biology without DNA or proteins. The hypothesis ...

New research at the Salk Institute now provides fresh insights on the origins of life, presenting compelling evidence supporting the RNA World hypothesis. The study, published in Proceedings of ...

The involvement of noncoding mRNAs in many regulatory processes, their abundance, and their diversity of functions has led to the hypothesis that an "RNA world" may have preceded the evolution of ...
