Transgenic inhibitors identify two roles for protein kinase A in Drosophila development.

abstract：:A genetic strategy identified Salmonella typhimurium strains carrying large (> 40 kb) Tn 10-catalyzed inversions; the inverted segments were characterized by XbaI digestion and pulsed field gel electrophoresis. Two size classes of large inversions were found. More than half of the inversions extended 40-80 kb either c...
