Transposons, or 'jumping genes' -- DNA segments that can move from one part of the genome to another -- are key to bacterial evolution and the development of antibiotic resistance. Researchers have discovered a new mechanism these genes use to survive and propagate in bacteria with linear DNA, with applications...
