Two other articles noting possible similarities between archean
and eukaryotic transcription machinery are:
Ouzounis & Sander. Cell 71:189 1992.
Creti et al. NAR 21:2942 1993.
(does someone have the complete Marsh citation handy?).
Perhaps we should wait until complete genomic sequences are available
from a eubacterium, archean, and eukaryote until we draw concrete
