‘Hitchhiking’ chromosomes yield new theory of cell division
Posted: January 24, 2006
Paragraph 1:
From the moment the cell was discovered, scientists have been dissecting the methodical, multi-step process by which they duplicate themselves. This week, Rockefeller researchers studying one component of this process — how a cell’s chromosomes move in preparation for division — announce a discovery that overturns current cell-division theory. Their findings, presented in the cover article of the journal Science, could one day be used to create a new class of cancer therapies.

Paragraph 5:
The standing theory for how chromosomes^ move to the center of a cell, or “congress,” held that they had to be bioriented, and the attached microtubules^ were responsible for pushing and pulling them into place. But now, using a unique combination of cutting-edge video microscopy, biochemistry^ and electron microscopy, Kapoor and Lampson found that this isn’t necessarily the case.
