Lab-Aids: Molecular Model of DNA and its Replication Kit

This basic introduction to the double helix model of DNA uses simple components developed exclusively by LAB-AIDS‚®. Those unique components include:‚ 
  • Double nitrogen pyrimidine bases are constructed proportionately larger in diameter than the single nitrogen purine bases 
  • Bases are linked by a unique hydrogen bond 
  • The deoxyribose sugar is pentagon-shaped, its actual structure 

Twelve eight-rung models can be constructed with each kit. Or, attach individual models together to form a giant double helix model that will be more than nine feet long! Includes 30 student worksheets, 1 instruction manual, and 12 packets of color-coded components.

Scientific Concepts:
  • Build a segment of the DNA molecule and see what a double helix is like
  • Model can be "unzipped" allowing for replication of DNA segment

  • 1 Teacher's Guide
