Thanks much!

They're probably OK, but it might be safest to run them by some of our 
prokaryote experts (Michelle, Jim, Debby, etc.). In the past everyone 
thought chromatin was a eukaryote-specific feature, and although that 
seems to be changing, I did a quick-n-dirty Google search, and found that 
there are still at least a few sources that say bacteria don't have 
chromatin (e.g. PMID:17148507). I don't know whether you think that's 
enough reason to choose different examples.

It seems OK as far as it goes -- what's there looks like enough to make 
the distinction for the relationship itself, and beating on it further 
probably wouldn't help.

I wonder whether it's worth saying any more about how has_part fits 
together with other relations in longer paths ... but even if so, this 
page isn't necessarily the place (nor are my thoughts on the subject fully 
formed).

Not that I know of. And I plan to declare my neutrality on the subject 
early and often.

I like it, and I think the part_of diagrams can (and should - consistency 
is a plus) use the same visual convention.
