DNA & Nucleotide Modeling: Single Group
kit #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.
- Individualize DNA model
- Build a molecular model of basic components of the nucleotides of RNA and DNA
