How to Make Your Own DNA Model?

You can make your own DNA model with small Styrofoam balls, paint, a dowel rod attached to a stand, and glue. The Styrofoam balls can be painted to represent the various types of molecules in your DNA string. Glue the first roll of molecules on the rod and use toothpicks to extend the balls out, if needed for your molecule pair. Continue building up the balls along your rod, using various colors to represent the DNA molecule you are modeling.
