|The natural enantiomer of the RNA precursor molecules |
formed a crystal structure visible to the naked eye
'These amino acids changed how reactions work and allowed only naturally occurring RNA precursors to be generated in a stable form,' said Jason Hein, leader of the Scribbens research team. 'In the end we showed that an amazingly simple result emerged from some very complex and interconnected chemistry.' The natural enantiomer of the RNA precursor molecules formed a crystal structure visible to the naked eye. The crystals were stable and avoided normal chemical breakdown. They can exist until the right conditions allow them to turn into RNA.
