We determined the identity elements of each tRNA isoacceptor for the three domains of life: Eubacteria, Archaea, and Eukarya. Our analyses encompass the most updated and curated available databases using an information theory approach. We obtained a collection of identity clusters for each of the isoacceptors of the 20 canonical amino acids for the three major domains of life. The identity clusters for all isoacceptors are compared within and among the three domains to determine their pattern of differentiation and to shed light on the evolution of the identity elements.

信息论揭示了在生活的三个领域中tRNA身份元素的进化。

我们确定了生活的三个域：真细菌，古细菌和真核生物每个tRNA异构受体的身份要素。我们的分析使用信息论方法，涵盖了最新和精选的可用数据库。我们获得了生命的三个主要域中20个规范氨基酸的每个同型受体的同一性簇的集合。在三个域内和域之间比较所有同型受体的同一性簇，以确定它们的分化模式并阐明同一性元件的进化。
