Lab-Aids™ Molecular Model of DNA and its Replication
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.
Manufacturer: Lab-Aids™ LAI71
DescriptionThis 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 respresenting 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, one for each group of two students.
Class size: 12 students.
|12 color-coded components packets containing: 16 Deoxyribose-sugar groups - black linkage; 16 Phosphate groups - white tubes; 8 Nitrogen (purine) bases: 4 Adenine (A) - orange tubes, 4 Guanine (G) - yellow tubes; 8 Nitrogen (pyrimidine) bases: 4 Cytosine (C) - blue tubes, 4 Thymine (T) - green tubes; 8 Hydrogen bonds - opaque rods. One teacher's guide; 38 student worksheets and guides|
