This part is associated with piggyBac transposon devices

piggyBac transposase is a popular enzymes that generates protein-DNA complexes called transposomes from DNAs flanked by "terminal repeats". These terminal repeats, or TR's, are specific cis elements. The transposomes are highly reactive and insert the DNA contained within them randomly into other DNAs (such as a genome).
