There has been a growing recognition that there are many conserved features among apparently diverse RNA splicing systems, suggesting that they may have a common origin. However, pre-tRNA splicing is an apparent exception in nearly all respects. Features of this unique class should be considered in any comprehensive discussion of the origin(s) of splicing and its implications for the evolution of gene structure.
人们越来越认识到，在明显不同的RNA剪接系统中存在许多保守特征，这表明它们可能有共同的起源。然而，前体tRNA剪接在几乎所有方面都是一个明显的例外。在任何关于剪接起源及其对基因结构进化影响的全面讨论中，都应考虑这一独特类别的特征。
