Human cells contain 23 pairs of chromosomes that form a loosely organized cluster in the cell nucleus. When cells divide, they must first condense these chromosomes—each of which when fully extended is a thousand times longer than the cell's nucleus and physically indistinguishable from the others—into compact structures that can be easily separated and packaged into their offspring.
