The origin of homochirality | Feature | Chemistry World
Today, the RNA world hypothesis is largely accepted: self-replicating RNA molecules were the precursor to DNA as the mode of inheritance, as they are simpler to synthesise. In 2009, John Sutherland, then at the University of Manchester in the UK, showed that chemical units that can be polymerised to make RNA can be synthesised from plausibly prebiotic starting molecules: cyanamide
