Which of the following statement is incorrect about RNA editing?
1
Editing reactions involve cleavage, insertions or deletions and ligation.
2
The 5" end of the guide RNA is characterized by a poly U-tail.
3
The RNA editing causes change in function of edited transcripts as compared to the unedited transcripts.
4
Editing is thought to occur in four stages: gRNA/mRNA duplex formation, cleavage of the mRNA at target site, the addition or deletion of U residues (mostly) in the mRNA and finally the re-ligation of the two fragments of the newly edited mRNA.
