In the original it's called Order 66, one of a number of contingency orders clones were trained to execute. For instance, Order 65 was to detain the Chancellor if he were found unfit to issue orders. Order 66 was to move against the Jedi if they threatened the Republic, which they had just did by trying to murder the Chancellor. Because they were essentially slaves bred for absolute loyalty and it was just one among many contingency orders the clones obeyed. And Palpatine was the shadow behind the creation of a clone army many years earlier so he had everything set.
