Many of us saw films in school and think of DNA replication -- the duplication of the cell -- as involving a gliding double-helix that breaks apart and smoothly forms new cells as symphonic music swells in the background. But the latest scientific studies show that cell replication is in fact much different, and far more chaotic. There can be a widespread substitution of different elements of the cell, with all sorts of effects. Those effects can be helpful, as in evolutionary change, or bad, as in cells that run amok and form cancer.
