Target site duplications refer to the duplication of part of the DNA sequence at the site of the insertion, with one copy of the duplication on each side of the element. Inverted terminal repeats refer to the repeated sequences found at the ends of some transposable elements. Target site deletions and inverted terminal duplications/deletions are not accurate descriptions of the outcome of IS element insertion.
