Jumping genes are called Transposon.
It is a nucleic acid sequence in DNA that can change its position within a genome, sometimes creating or reversing mutations and altering the cell's genetic identity and genome size.
Transposable elements make up a large fraction of the genome and are responsible for much of the mass of DNA in a eukaryotic cell.
Transposons are also very useful to researchers as a means to alter DNA inside a living organism.
