Molecular Model of DNA and its Replication


Availability: In stockQuantity:100


Quick Review:

  • 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


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.
