Modeling a Spiral DNA Molecule

In this tutorial we will model a DNA molecule. There are several ways to do this; which approach you choose will depend upon the exact look you want to achieve: a twist, a spiral, a helix, etc. Here, I will demonstrate an “old school” spiral method that is very effective. Some other approaches may be a bit faster, but this one is very controlled, and also may introduce you to a modeling technique you will find helpful for other projects.
