Double Helix Student Modeling Pack

Students can individually explore the basics of DNA structure and replication with the hands-on models and digital activities in our Double Helix Student Modeling Pack.

  • Examine the structure of color-coded DNA bases showing purines and pyrimidines and connect to a continuous sugar-phosphate backbone.
  • Discover the directionality of each backbone strand.
  • Explore hydrogen bonding in A-T and G-C base pairs.
  • Build double-stranded DNA and twist into the double helix.
  • Model the process of replication.
