DNA transposons are clearly delineated segments of DNA that have the ability to move about within a genome in a process known as transposition. Non-replicatioe, cutand-paste transposons are mobilized by the complete excision of the transposon from the genomic DNA, thus creating a DNA double-strand break at the transposon donor site. The P element transposon of Drosophila melanogaster transposes by a cut-and-paste mechanism, thereby providing a rich experimental system to study the repair of DNA double-strand breaks at a specific location in the genome.DNA transposons are clearly delineated segments of DNA that have the ability to move about within a genome in a process known as transposition.
