Bearing witness to the phenomenon of symmetric cell division

[unable to retrieve full-text content]For more than 125 years, scientists have been peering through microscopes, carefully watching cells divide. Until now, however, none has actually seen how cells manage to divide precisely into two equally-sized daughter cells during mitosis. Such perfect division depends on the position of the mitotic spindle (chromosomes, microtubules, and spindle poles) within the cell, and it?s now clear that human cells employ two specific mechanisms during the portion of division known as anaphase to correct mitotic spindle positioning.
