viral RNA editing
The process by which bases in viral mRNA are chemically altered during viral transcription. This is usually the incorporation of 1 - 6 additional nucleotides, which shifts the reading frame, allowing the generation of different protein products or through a specific nucleotide change that eliminates the termination codon.
