Examples
- Rna heterogeneous nuclear rna , hnrna
核内异质 - Rna polymerase i synthesizes the three largest rrnas . rna polymerase ii mainly produces mrna encoding proteins and most of sn rnas , and rna polymerase iii makes 5s rrna and trna , as well as a few small nuclear rnas . the transcription sites of the polymerases have been studied since early 1980s
真核生物细胞核中有三种rna聚合酶，即rna聚合酶、和，它们分别转录产生不同的rna ，其中rna聚合酶( pol )转录合成45srrna前体；聚合酶( pol )转录合成mrna前体及大多数snrna ；聚合酶( pol )转录合成5srrna 、 trna和一些小分子rna 。 - Rna polymerase synthesizes the three largest rrnas , 5 . 8s , 18s and 28s rrna . rna polymerase mainly produces mrna encoding proteins , and rna polymerase makes 5s rrna and trnas , as well as a few small nuclear rnas . the transcription sites of the polymerases have been studied since early 1980s
在细胞中它们的功能各不相同： rna聚合酶负责催化合成5 . 8s 、 18s和28srrna ， rna聚合酶主要负责mrna的转录合成，而rna聚合酶则负责催化5srrna 、 trna 、多数的snrna以及某些病毒基因(如va基因)等的转录。
