Sorry to pick on one sentence, but yes, even vaccinia and herpesviruses
are incredibly streamlined. What's a mere 76 proteins (herpes simplex
virus) or, what, 250 or so in vaccinia, compared to hundreds of thousands
in humans, or (I don't know much about bacteria) thousands in bacteria.
One of the reasons viruses have been so popular as model systems
is that they are streamlined. The biggest viruses I know of are only
300,000 - 400,000 bp long.
