title: Mechanisms of transposition in bacteria.
abstract: The transposable elements of bacteria are diverse in size, functional arrangement, DNA sequence, and in their modes of transposition. We review here data suggesting that the kanamycin-resistance transposon Tn5 moves without replicating (conservative transposition), but the ampicillin-resistance transposon Tn3 is duplicated when it transposes, and that both the chloramphenicol-resistance transposon Tn9 and bacteriophage Mu are replicated in some events but not in others. A model is presented in which conservative and replicative transposition are alternative branches of a single pathway.
