RNA World May Have Started Spinning with Triplet-Based Synthesis

RNA World models tend to stall at a crucial point: the genetic replication of folded RNA structures. Since these structures include ribozymes, the very elements that carry out replication, RNA World models need some sort of kickstart, a plausible mechanism whereby folded RNAs may be replicated.Such a mechanism, suggest scientists based at the Medical Research Council (MRC), needn’t be anything like the one-base-at-a-time syntheses observed in today’s lifeforms. No, a three-base-at-a-
