DNA Modeling: Molecular Structure & Replication
kit #71
This basic introduction to the double helix model of DNA uses simple components developed exclusively by LAB-AIDS®:
? 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, a Teacher's Guide, and twelve packets of color-coded components. Additional sets of molecular model components are available as ADD A GROUP item # 71EL.
- 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
