'Ribo-organisms' of the primordial RNA World would have needed ribozymes that catalyze RNA replication. McRae, Wan, Kristoffersen et al. recently revealed how these RNA replicases might have functioned by solving the structure of an artificial polymerase ribozyme. This work illustrates how complex RNA structures evolve, with implications for the origins of life.
原始 RNA 世界的“核酶生物”可能需要核酶来催化 RNA 复制。最近,McRae、Wan、Kristoffersen 等人通过解决人工聚合酶核酶的结构,揭示了这些 RNA 复制酶可能的功能。这项工作说明了复杂的 RNA 结构是如何进化的,这对生命起源具有重要意义。
