I think you're right about viruses--they have some very clever
information compression schemes. Although I cannot rule out the possi-
bility that there are active genes on both strands, I think that this
does not occur for humans. One of the many experts in this field should
be able to make more definitive comments.
I do not think anyone knows how most of the non-translated parts
of the genome (called "junk DNA" at one time) act to regulate gene ex-
pression, or whether such regulation is restricted to one or the other
strand. I would guess that there is some functionality in the antisense
strand, but that is strictly speculation on my part.
