Composite transposon
A transposible element flanked by two copies of an IS element.
Concatamer
An end-to-end (tandem) array of identical DNA rnolecules; a repeated polymer of DNA.
A DNA composite transposon.
Transposons are sequences of DNA that can move around to different positions within the genome of a single cell, a process called transposition.
The transposase gene is flanked on either side by fifteen to twenty-five base pairs, arranged as "inverted repeats." A composite transposon is composed of any gene sandwiched between two IS sequences; this entire unit will move.
