This intertwined strand structure teaching model is designed as a clear visual aid for biology and genetics lessons. Built from EVA, it features a translucent spiral body that makes the overall spiral shape easy to see and discuss in class or during self-directed study. The freestanding round blue base gives the science model stable support, so it can be placed on a educator's desk, bookshelf, or classroom display area without needing extra mounting. Its balanced presentation helps keep attention on the structure itself while allowing convenient everyday use. Colorful paired rods labeled A, thymine, and C provide an accessible way to show how base pairs are arranged in a model. This makes it easier to point out relationships between the components and explain the fundamentals of structural structure in a simple, direct way. As a double spiral model, it serves as a practical classroom reference for introducing genetics concepts and reinforcing visual learning. The included instruction booklet adds helpful guidance, making the heredity model more ready for instructional moments, student demonstrations, and study meetings where a clear scientific display is important.
