This basic bilingual English/Spanish 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.
