RNA editing is a widespread mechanism for post-transcriptional modification of the base sequence of mRNA. In humans, RNA editing
A) is mediated by guide RNAs and a multiprotein complex called the "editosome" that inserts or deletes uridines.
B) occurs by deamination of adenosine to inosine, or cytidine to uridine.
C) is mediated by small nucleolar RNAs and base modification enzymes.
D) is mediated by the U12-type intron splicing pathway.
