Lab-Aids:‚ Advanced Molecular Model of DNA and its Replication Kit
Advanced modeling kit explains DNA double helix model in greater detail, and emphasizes construction of the nucleotides (the phosphate group, deoxyribose sugar, and one of four bases). While replication is observed, protein synthesis, transcription, and translation are not illustrated. Twelve, nine-rung models can be constructed with each kit.
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
