Tn10

Tn 10 is a transposable element. This element can move from position to position on the chromosome or plasmid by cut and paste transposition. Being a composite transposon, it is flanked by insertion sequences. In Tn9 they are orientated in the same direction with respect to each other, but in Tn5 and Tn10 the insertion sequences are opposed in orientation. Between the Tn10 insertion sequences there are a number of genes icluding one conferring tetracycline resistance.
