| Two things really
stick in students minds about "learning" mitosis. First,
the photos and movies we saw were really fascinating. Second, the
details seemed really daunting, even if they weren't as
"bad" as meiosis. But asking "How?", about any of
that really brings up the complicated and interesting
parts.
So, C.
elegans (shown here) doesn't have a centromere. Plants
don't have centrioles. Spindle fibers have to actually attach to
something, they have to be able to apply an actual physical force,
and when they appear to shorten, they actually do. How? Check out Kelly Dawe's
research at the University of Georgia.
Moreover, even
the relative positions of the chromosomes appears
not to be random, and there is a memory of position from division to
division. Indeed!
