Nucleotide Modeling: An Introduction to DNA & RNA
Students use a molecular modeling set to build molecules of ribose, deoxyribose and five different nitrogen bases. They use this modeling experience as a basis for visualizing and understanding some of the major differences between DNA and RNA.

Kit #71-513Individual DNA Model
This kit is for a single group and combines the activities of two full-class (16 group) kits: #71 DNA Modeling: Molecular Structure & Replication and #513 Nucleotide Modeling: An Introduction to DNA & RNA. In Activity I (from Kit #71) students build models of DNA and use this experience to visualize the structure of DNA molecules as a ...

Kit #71DNA Model
The two activities in this kit introduce students to the structure of the DNA molecule and how its structure allows it to replicate. Using a unique Lab-Aids modeling set, students first build an 8-rung DNA double helix and learn the base-pairing rule. Then starting with a 4-rung segment, they unzip the ladder and create...

Kit #72Protein Synthesis Model
The purpose of this kit is to model the production of proteins and compare the structure of DNA and RNA. Activity 1 models the structure of DNA from its nucleotide to double helix and its replication. Activity 2 introduces RNA and its nucleotides and simulates the process of transcription in the nucleus and translation in the...

Kit #70Genetics Concepts
This activity allows students to collect data that show similar patterns to those Mendel discovered. Using specially designed equipment, students “rediscover” the principles of genetics. The unique materials produce random genotype combinations that are statistically consistent with those found when studying living organisms.
