 <p align-text="justify"> RNA editing is a post-transcriptional phenomenon
 involving the insertion/deletion or substitution of specific bases in precise RNA localizations.

+In humans, RNA editing occurs by deamination of cytosine to uridine (C-to-U) or mostly by the
 adenosine to inosine (A-to-I) conversion through ADAR enzymes. A-to-I substitutions may have
