Mighty microscopic fibers are the key to cell division and life itself
Every second, millions of cells in your body divide in two. In the space of an hour, they duplicate their DNA and grow a web of protein fibers around it called a spindle. The spindle extends its many fibers from the chromosomes in the center to the edges of the cell. Then, with extraordinary force,...
