a: Dna ~
b: a spiral staircase
What: "DNA is like a spiral staircase, with each step of the staircase rising 0.34 nanometers and turning 36 degrees. Once you know how to build a single step and how each step connects to the next, you can build a molecule model of any length by just stacking copies of the step."
