That is the tone of Molecular Biology Made Simple and Fun .

The best PDFs use . Look for illustrations where molecules have faces or where metabolic pathways are drawn as subway maps. If the PDF uses only stock photos of double helixes, it is not fun.

If you remember that a gene is a recipe for a protein , you are already 50% ahead of the average pre-med student.

That instinct—to demand fun and simplicity—is not laziness. It is intelligence. It is the recognition that complex ideas are only complex until you find the right metaphor, the right drawing, or the right story.
