What's the Right Answer?

I used to teach molecular biology, and an graduate level molecular biology. And i realized every year for 15 years I had to review that stuff before i taught it - which meant i didn't memorize it. Why am i making everyone else memorize it when really i need to be talking to them about the big picture ideas of how does a plant behave? Doly: The students want to know at the end what the right answer is. There is no right answer, but it's just killing em.
