그런 다음 성숙한 mRNA(mature mRNA)는 번역을 위해 핵을 빠져나갑니다. (jove.com)
Mature messenger RNA, often abbreviated as mature mRNA is a eukaryotic RNA transcript that has been spliced and processed and is ready for translation in the course of protein synthesis. (wikipedia.org)
Unlike the eukaryotic RNA immediately after transcription known as precursor messenger RNA, mature mRNA consists exclusively of exons and has all introns removed. (wikipedia.org)
The production of a mature mRNA molecule occurs in 3 steps: Capping of the 5' end Polyadenylation of the 3' end RNA Splicing of the introns During capping, a 7-methylguanosine residue is attached to the 5'-terminal end of the primary transcripts.This is otherwise known as the GTP or 5' cap. (wikipedia.org)
Beyond this, the 5' cap has also been shown to have a role in exporting the mature mRNA from the nucleus and into the cytoplasm. (wikipedia.org)
As a part of the maturation process, RNA splicing removes the non-coding RNA introns leaving behind the exons, which are then spliced and joined together to form the mature mRNA. (wikipedia.org)
