Budding wing from irradiated fruit fly larvae, magnified about 80 times; various aspects of apoptosis in a regular fly (left column) are compared with the mutant fly lacking the drice gene (right column). Upper row: “reporter” proteins are highlighted with green fluorescent protein; middle row: the cutting up of these reporter proteins by caspases; bottom row: numerous cells die by apoptosis in the regular fruit fly (left), whereas almost no apoptosis occurs in the fly lacking the Drice caspase (right)
