Product overview This DNA model is a colorful, plastic assembly kit designed for teaching and learning basic DNA structure. It presents the double helix and base pair relationships in a clear, tangible format suitable for school and university biology courses. The product meets national Ministry of Education standard JY35 81 technical conditions for DNA structure models. Key features and benefits Clear visualization: Colorcoded components represent the double helix and nucleotide pairing, making abstract molecular concepts easier to see and understand. Handson learning: The DIY assembly and disassembly process turns complex structure into a practical activity that reinforces classroom lectures and readings. Durable material: Constructed from plastic for repeated classroom handling and transport between lab and lecture. Complete kit: Includes all small accessories required to build the double spiral DNA structure, so no additional parts are needed for assembly. Standards aligned: Intended for ordinary school and university basic course biology teaching use, consistent with the JY35 81 technical conditions. Compact package: Supplied as a single DNA model that is easy to store and reuse for multiple lessons. Specifications Item type: DNA Model Material: Plastic Use: Teaching aid for basic biology and genetics; conforms to national Ministry of Education standard JY35 81 DNA structure model technical conditions production. Package contents: 1 x DNA Model Practical applications and scenarios Classroom demonstration: Use the model during lectures to show the double helix, base pairing, and the spatial arrangement of nucleotides. Laboratory practice: Provide students with a tactile assembly exercise to reinforce concepts in genetics labs or basic molecular biology sessions. Study and projects: Support group projects, science fair displays, or individual study by allowing learners to construct and review the DNA structure independently. Why choose this model The model converts molecular geometry into a visible and manipulable form, helping students bridge the gap between textbook diagrams and threedimensional structure. Its simple assembly, complete accessory set, and alignment with educational standards make it suitable for regular classroom use and supplemental study.
