At the Biology of Genomes meeting, a geneticist reported what seems to be a new way that a cell shuffles its genes around: by forming a loop of DNA that then breaks apart in a different place before inserting into a different chromosome. So far, this circle-driven, gene-shuffling mechanism has been found only in cattle, but researchers are now wondering if it will prove to be common and are looking for examples in humans.
