IF-statements: An IF statement executes the code in a subsequent code block if some specific condition is met. Cell chemistry can impact production of the protein strings DNA codes for and can impact if they are even functional. Not a programmer, so maybe that's not a good analogy. But it's what came to mind as an amateur student of "Exactly how do my defective genes make my life a living hell?"
