The origin and evolution of translational machinery — which produces a specific peptide from an RNA sequence — is a major unsolved puzzle in prebiotic chemistry. Now, the coupling of amino acids directed by RNA templates in the absence of a ribosome provides clues on how this protein synthesis process might have started.

翻译的起源

翻译机制的起源和进化——从 RNA 序列产生特定的肽——是益生元化学中一个主要的未解决的难题。现在，在没有核糖体的情况下，由 RNA 模板引导的氨基酸偶联提供了有关这种蛋白质合成过程可能如何开始的线索。
