Abstract
A mobile bacterial group II intron can integrate into DNA by the reverse splicing into a target site of its RNA transcript, which then acts as a template for DNA synthesis by an encoded reverse transcriptase. Mobility does not require homologous recombination, which has important practical and evolutionary implications.
