title: RNA sex.
abstract: Recombination of genetic information is a major driving force in evolution, today catalyzed by protein enzymes. In this issue of Chemistry & Biology, a paper by Riley and Lehman demonstrates that RNA can perform general recombination of RNA strands, thus supporting the scenario of a prebiotic RNA world.
