|Cryptogene||A gene whose transcript is edited.|
|Guide RNA||(aka gRNA) A short 3'-uridylated RNA that can form a perfect duplex (except for the oligo[u] tail) with a stretch of mature edited mRNA. G-U base pairing is allowed.|
|Anchor Duplex||The RNA duplex formed by hybridization of the 5' end of the gRNA and the mRNA sequence just downstream of the first editing site in an editing block.|
|Pre-Edited||A pre-edited region or sequence will be edited in the mature mRNA.|
|Unedited||An unedited region or sequence will never be edited in the mature mRNA.|
|Editing Block||Edited mRNA sequence mediated by a single gRNA.|
|Editing Domain||Edited mRNA sequence mediated by two or more overlapping gRNAs.|
|Pan-Edited Gene||Extensively edited.|
|3' oligo[U] Tail||The string of non-encoded U's at the 3' end of the gRNA|
|gRNA-mRNA||A gRNA-mRNA chimera consists of a gRNA 5' end covalently bound to an mRNA 3' end, oft at an editing site.|
The gRNA's A's and U's guide addition of U's to the mRNA.
If the mRNA's U's are not base-paired in the gRNA, they are removed.
