FeatureHow RNA reveals clues to life’s origins on Earth
The discovery of catalytic RNA transformed our understanding of life’s beginnings. Clare Sansom explores how the RNA world hypothesis bridges the gap between non-living chemistry and the first cells

OpinionCracking codons
Understanding how chemistry links RNA triplets to the properties of amino acids
-
OpinionFrom prebiotic soup to fine-grained RNA world
Theories about how life emerged need to be closely attuned to conditions on the early Earth
