abstract：:Measles virus transcription generates multiple P/C gene-specific mRNAs by a process which has been termed editing. In one of these mRNAs, the cotranscriptional addition of a single nontemplated G residue allows translational access to the V protein reading frame. The protein translated from this mRNA has been called V...
