Post transcriptional modification
中文百科
转录后修饰 Post-transcriptional modification（重定向自Post transcriptional modification）
    转录后修饰（RNA修饰，或称修饰RNA）是真核细胞中，将初级转录RNA转化为成熟RNA的加工过程。一个很好的例子就是前mRNA转化为成熟的mRNA，其中包括剪接，并发生在蛋白质生物合成之前。这一加工过程对于真核生物基因组的正确翻译至关重要，这是因为真核生物的初级转录RNA中包含既包括用于编码蛋白质的外显子又包含非编码的内含子。

Post-transcriptional modification 转录后修饰（重定向自Post transcriptional modification）
Post-transcriptional modification or Co-transcriptional modification is a process in cell biology by which, in eukaryotic cells, primary transcript RNA is converted into mature RNA. A notable example is the conversion of precursor messenger RNA into mature messenger RNA (mRNA), which includes splicing and occurs prior to protein synthesis. This process is vital for the correct translation of the genomes of eukaryotes, including humans, because the primary RNA transcript that is produced, as a result of transcription, contains both exons, which are either coding sections of the transcript or are important sequences involved in translation, and introns, which are the non-coding sections of the primary RNA transcript. |
