An analysis of enzymes that load amino acids onto transfer RNAs - an operation at the heart of protein translation - offers new insights into the evolutionary origins of the modern genetic code, researchers report. Their findings appear in the journal PLOS ONE. The researchers focused on aminoacyl tRNA synthetases, enzymes that "read" the genetic information embedded in transfer RNA molecules and attach the appropriate amino acids to those tRNAs...
