Do viruses have introns? According to one question in the TPR, they do. However, I cannot find any source that states the same. Thanks!
High-risk human papillomaviruses (HPVs) encode two viral oncoproteins, E6 and E7, from a single bicistronic pre-mRNA containing three exons and two introns.

I guess it depends how you describe an intron. there are intergenic stretches and there are splice variants where some AAs get taken out of a primary transcript, but there's no real rubbish areas.
look up HIV Rev's function for a good example of "introns"
don't know what I was thinking there.. post translation instead of mRNA.Nucleotides are removed from transcripts, not amino acids.
An intron could be defined as a sequence that is removed from a pre-mRNA transcript by the spliceosome. These are certainly present in both HIV and HSV, to use two examples. I don't know why we have people continuing to post in this thread with uninformed speculation when all this has already been covered.
