Transposons, mobile DNA elements found in the genomes of prokaryotic and eukaryotic organisms, move randomly from one site in a chromosome to another using a process catalyzed by transposases. This process, called transposition, occurs naturally but infrequently in cells as a means of genetic change. For many years scientists have used transposons for genetic research. A new system, combining Tn5 transposase and a Tn5-derived transposon to form a stable synaptic complex, forms the basis of EZ::
