In a paper in this week's issue of Science, Voloshin et al. (p. 868) show that a 20-amino acid peptide from RecA, a bacterial protein that repairs and recombines DNA, can mediate DNA strand exchange—one of the functions of the RecA protein. Stasiak discusses why this result is surprising and what the rest of the RecA protein is for.
