Study sheds light on DNA sculpting properties of enigmatic protein

Sometimes, when something is broken, the first step to fixing it is to break it even more. In a recent example, scientists seeking to understand the mechanism of a DNA-repairing enzyme have discovered that the molecule performs its functions by first marking and then further breaking damaged DNA.
