Deletion scanning of the regulatory sequences of the Fbp1 gene of Drosophila melanogaster using P transposase-induced deficiencies.

abstract：:Knowledge of multigenic family organization should provide insight into their mode of evolution. Accordingly, we characterized the 5S ribosomal gene family in the Drosophila melanogaster strain ry506. The 5S genes in this strain display a striking HindIII restriction difference compared to the "standard" D. melanogast...
