1·RNA splicing is carried out by the spliceosome, which is a large, dynamic complex composed of more than a hundred proteins and several small nuclear RNAs.

RNA剪接是由一个上百个蛋白质和数条小核r NA组成的复杂的动态复合体完成的。

2·Alternative splicing didn't help either: it could be argued that it represents a case of RNA making itself, then making a bunch of different proteins.

选择性拼接也不肯帮忙：它可以被看作另外一种例外——RNA还能自我复制，然后制造出一揽子形形色色的蛋白质。

3·Some investigations on the ciliated protozoan have provided the insights into the mechanism of ribozymes, self-splicing RNA, telomere structure and function, DNA sequence reorganization and so on.

通过对它的研究，人们发现并且掌握了核酶的分子机制、RNA的自我拼接、端粒的结构和功能、DNA序列重组等机理。
