It became possible to genetically modify Drosophila melanogaster using recombinant DNA methods in 1982 when P elements (described below) were identified and genetically altered to serve as mechanisms (vectors) for inserting genes into the nuclear genome of Drosophila. The use of P-element vectors provides a powerful tool that has modernized Drosophila genetics and made it possible to study the role of many genes important in development and behavior. In addition, the P-element system has served as a model for scientists wanting to genetically modify other insects for use in pest management programs ( Transgenic Insects).

P Elements are Disposable Elements

P elements are transposable (movable) elements that have been harnessed as a tool for genetically modifying the fruitfly Drosophila melanogaster in a consistent manner. Transposable elements are independent genetic elements that can move within and between genomes; some call them selfish genetic elements. The development of P...
