Transposition requires three DNA sites on the transposon: two at each end of the transposon called terminal inverted repeats and one at the target site. (wikipedia.org)
In many reactions, the transposon is completely excised from the donor site in what is called a "cut and paste" transposition and inserted into the target DNA to form a simple insertion. (wikipedia.org)

Cut-and-paste transposition does not cause an increase in the number of transposons per se: there is one copy at the start and one copy at the end. (wikimili.com)
However, the transposon has a mechanism to favor transposition immediately after a replication fork passes through, leaving a hemimethylated copy of Tn 10 on each sister chromosome . (wikimili.com)
Since transposition is favored when Tn 10 is hemimethylated, the transposon on one sister chromosome can hop somewhere onto the other chromosome so that two copies of the transposon end up on one chromosome. (wikimili.com)
