Abstract

Several repetitive sequence elements from diverse species share extensive sequence homology with tRNA molecules. Analysis of the tRNA-like sequences within these elements suggest that they have originated from authentic tRNA sequences. Elements containing tRNA-like sequences can be divided into three distinct groups whose members share extensive sequence homology, have similar sequence organization and have unique species distribution. We suggest that these three groups represent independent examples of retroposon families that have originated from tRNAs.

摘要

来自不同物种的几个重复序列元件与tRNA分子具有广泛的序列同源性。对这些元件中类似tRNA的序列分析表明,它们起源于真实的tRNA序列。含有类似tRNA序列的元件可分为三个不同的组,其成员具有广泛的序列同源性、相似的序列组织且具有独特的物种分布。我们认为这三个组代表了起源于tRNA的反转录转座子家族的独立实例。
