mRNA must be edited before it can leave the nucleus. This editing includes A splicing. B the addition of a 3' poly-A tail. C the addition of a 5' G cap. D All of the above are included in editing.

Step 1
This cap is added to the 5' end of the mRNA molecule and helps protect the mRNA from degradation and aids in the initiation of translation. Show more…

Premature mRNA must be processed before it can leave the nucleus. All of the following are examples of post-transcriptional processing EXCEPT: 5' cap must be added Poly A tail is added to the 3' end Introns must be removed Adenines must be added to the 5' cap, this is called the Poly A tail
Adi S.
The modification of mRNA (editing/splicing) occurs before translation. It involves the removal of the cap from the 5' end and the removal of the tail from the 3' end of the mRNA. Additionally, it involves the removal of exons and the joining of introns together to form the mature mRNA. This process occurs in both eukaryotic and prokaryotic cells. Furthermore, it involves cutting out exons, with each exon becoming a separate "mature" mRNA.
