These duplications were generated by transgenic methods and are generally five to twenty genes in size. They are useful for mapping, gene rescue and changing the dosage of X-linked genes. The duplications consist of 70-120 kb segments of the X chromosome integrated into an attP site (most duplications are inserted into PBac{y[+]-attP-3B}VK00033 at 3L:6435776 (65B2)). The DC duplications are described in Venken et al. (2010). The transformation system was described in Venken et al. (2006). The transformed X chromosome segments originated in BAC libraries described in Venken et al. (2009). See the Bellen lab P[acman] Resources site for more information.
