title: Mechanistic insight from chaos: how RecA mediates DNA strand exchange.
abstract: Cleverly designed single-molecule FRET experiments reported in this issue of Structure by Ragunathan et al. coax RecA to reveal some of its secrets. Observing individual events identifies intermediate steps and provides clues for how to drive strand exchange forward.
