Abstract

The recent discovery of self-splicing introns in cyanobacteria has given renewed interest to the question of whether introns may have been present in the ancestor of all living things. The properties of introns in genes of bacteria and bacteriophages are discussed in the context of their possible origin and biological function.

摘要

最近在蓝细菌中发现了自我剪接内含子，这重新引发了人们对于内含子是否可能存在于所有生物祖先中的问题的兴趣。细菌和噬菌体基因中内含子的特性在其可能的起源和生物学功能的背景下进行了讨论。
