Which of the following mechanisms is used by SV40 to produce several proteins from a single transcription unit?

Question

Quizplus · Accepted Answer

SV40 uses alternative mRNA splicing to produce multiple proteins from a single transcription unit. This allows for the generation of different protein isoforms from a single primary mRNA transcript via the inclusion or exclusion of different exons during splicing. The other mechanisms listed (alternative start codons, RNA editing, and ribosomal frameshifting) can also produce multiple protein isoforms, but are not used by SV40.
