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

Scientists in the 1960s, including Salk Fellow Leslie Orgel, proposed that life began with the "RNA World," a hypothetical era in which small, stringy RNA molecules ruled the early Earth and ...

The RNA world hypothesis gains support from the in vitro evolution of a bifunctional ribozyme that can recognize an activated glutaminyl ester and subsequently aminoacylate a tRNA molecule.

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 ...

Their discoveries have real-world implications, as Eterna crowdsources RNA designs, helping scientists better understand gene expression, disease prevention, and more. The NOVA RNA Lab supports ...

and it has pretty important implications for the RNA world theory,” he added. Study coauthors Gerald Joyce and David Horning of Scripps began with a variant of the ... Experts from the Women’s Brain ...

Researchers have now uncovered the 3D structure of the RNA enzyme SAMURI. Their study provides insights into the development of ribozymes and the evolution of catalytically active RNA. Researchers ...
