would want my name on it. This papers, and others in the near future to
come from Europe shows one way to do a mini-mega sequencing project.
Many (in the human and C. elegans) project have made fun of the Yeast
project but the Nature paper has silenced many, and it works! We can
sequence a small genome (14,000,000 bp +/-) by "conventional" cloning and
sequencing methods. They will not be able to do this for the human genome
project ... they will need new technology.

is more like 4 ... I, II, III (finished) and XI.

and there are probably more, and some of the already identified ones may
be bogus. Many carreers are spent on a single gene ... so more than 180
for CHIII and more than a thousand (2000?) for the yeast genome will keep
many many people very busy. The task of genome sequencing is very
altruistic (well, I think it is ;-). We are producing data which will be
used (and corrected!) by thousands of scientist worldwide, and not just

I think you meant very few introns here (?) ... and yes, not much
"chance" in choosing yeast here ... if I can quote somebody from my yeast
mailling list (yes, yes, it is comming folks ;-) ...
