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! For more "options" on how to do the anaphase thing, check this out.
