What keeps the machinery for chopping functional pieces out of certain long RNA strands from cutting up the wrong kinds of RNA?
 

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)
