I like Mike's suggestion of identifying the weirdest eukaryotic cell. Although
there are lots of good candidates, I must chauvinistically vote for
Pneumocystis carinii, which has only a single rRNA gene repeat on one of its
chromosomes. Does anyone know of another such case?
It also cannot be grown axenically yet is plentiful in ambient air, has a
vegetative phase resembling protozoa but molecular taxonomy clearly identifies
it as a fungus, and has mutiple casettes for major surface glycoproteins which
superficially resemble gene regulation in trypanosomes.
I'll bet some of you can top that.
