DNA Structure

An Interactive Animated Nonlinear Tutorial by Eric Martz
Adapted to Jmol and JSmol by Angel Herráez
Part of the Biomodel website by Angel Herráez, Univ. de Alcalá (Spain)

A. Double helix by element: base pairs, hydrogen bonding	B. The Code Explanation of codons and anticodons
C. Strands and helical backbone	D. Ends and antiparallelism

This tutorial is designed to complement Biology or Biochemistry and Molecular Biology books, so it is not by itself a complete introduction to DNA structure.

1. This tutorial is designed to complement an introduction to DNA, by providing tools for a self-directed exploration. It does not tell a story (but does offer questions for students and a lesson plan for teachers, see below). As a preamble to the tutorial, or for a story that introduces DNA structure with interactive molecular graphics, we recommend
   • DNA Structure in Biomodel-3 (basic level, adequate for secondary school).
   • DNA Structure in Biomodel-1 (advanced level).
   • Exploring DNA Structure by Andrew Carter (Jmol version by Frieda Reichsman).
2. The Animated Interactive Tutorial Pages (A, B, C, D): please visit the 4 sections in the colored panels.
3. Questions for Students and a Lesson Plan for Teachers.
   More Molecules for High School Teachers.
