All of the choices are correct. A transposon is a mobile genetic element that can insert itself at one or more sites in a genome, causing mutations in genes or chromosomal rearrangements. It is called a "jumping gene" because it can move from one location to another in the genome, and it may or may not leave a copy of itself in its original site when it moves.
