mRNA metabolic process
mRNA modification
mRNA editing
The term 'RNA editing' (GO:0016547) was merged into 'RNA modification' (GO:0009451) on the basis of statements in the preface of Modification and Editing of RNA (ISBN:1555811337) that there is no clear distinction between modification and editing. Parallel changes were made for substrate (e.g. tRNA, rRNA, etc.) specific child terms of 'RNA editing'.
The covalent alteration of one or more nucleotides within an mRNA molecule to produce an mRNA molecule with a sequence that differs from that coded genetically.
