DNA Teaching Tool

This model of a DNA strand was designed to help teach introductory genetics concepts to high school students. The bases and backbone lock together, and the complementary base pairs have corresponding shapes (but do not interlock, to allow for easier manipulation and to represent the weaker hydrogen bonding between them). All of the pieces have debossed labels, which are oriented to allow rotation of the pieces.

The included profile will print a class set of models - 10 sets that each have 12 sugar-phosphate backbone pieces, and 4 of each of the nitrogenous bases. (Print plate 1 twice, and the other plates once each.)

I designed this kit to use with my own high school classes, and hope that it can be useful for other teachers.
