DNA and Nucleic Acid Model Kit, Single Kit

LAB 71-513

This kit allows a student to construct a model of an 8-rung ladder segment of a DNA molecule and then build a molecular model of the basic components of the nucleotides of RNA and DNA


This Lab-Aid combines the features of the Molecular Model of DNA and its Replication (LAB-AIDS® No.71) and Nucleic Acid Molecular Structure (LAB-AIDS® No. 513) for an individual student. All components are reusable and the nucleotides (when using more than one kit) can be linked together to form a DNA model. A set of instructions for constructing the models is included with each packet. This activity is an excellent review of these concepts.

Kit Includes:

  • 1 Student Instruction Manual
  • 4 Adenine (A) (orange)
  • 49 Covalent plastic bonds
  • 4 Cytosine (C) (blue)
  • 16 Deoxyribose sugar groups (black)
  • 4 Guanine (G) (yellow)
  • 8 Hydrogen bonds
  • 16 Phosphate groups (white tubes)
  • 19 Single electron hydrogen atoms (white)
  • 10 Carbon (black), tetrahedral centers
  • 5 Nitrogen (red), tetrahedral centers
  • 11 Oxygen (blue), tetrahedral centers
  • 1 Phosphorous (purple), tetrahedral centers
  • 4 Thymine (T) (green), tetrahedral centers

Scientific Concepts:

  • Individualize DNA model
  • Build a molecular model of basic components of the nucleotides of RNA and DNA

Classroom Planning:

  • Number of groups: 1
  • To complete the two activities in this kit requires two to three ~50-minute class periods.
