Molecular Model of DNA and Its Replication Kit

LAB 71
Lab-Aids

This basic introduction to the double helix model of DNA uses simple components developed exclusively by LAB-AIDS®.

$121.00

 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. Additional sets of molecular model components are available as ADD A GROUP item # 71EL.


Kit Includes:

  • 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
  • 36 Student Worksheets and Guides
  • 1 Teacher’s Guide


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


Classroom Planning:

  • Number of students: 36
  • Number of groups: Maximum 12 groups per period
  • To complete this kit requires one ~50-minute class period
