Percent coding?

Tim Lindblom (lindblom at zookeeper.zoo.uga.edu) asks about current
percentages of predicted coding vs noncoding regions in C elegans.
Here is some information from the genome sequencing project.  

It appears to vary with region, not surprisingly, and you should
remember that we are aiming to sequence gene rich regions.  For one
1.7Mb region 31% of the sequence is coding (i.e. in exon).  We have
another 400kb region that is about 37% coding.  I don't have a
figure for everything sequenced so far, but expect that it would be
biased because the region we are sequencing appears to be relatively
gene dense.  I would predict an average value of well under 30% for the
whole genome.
