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 representing its actual molecular 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 36 student worksheets, 1 instruction manual, and 12 packets of color-coded components.
