Trademark Scientific DNA Helix Model - 23.5" Double Helix Classroom Science Tool

About This Product

Science teachers and students, this DNA helix model is perfect for making genetics and biology lessons come alive. Standing 23.5 inches tall with a 20-inch diameter base, it's substantial enough for classroom demonstrations but not overwhelmingly huge. The double helix structure is fully assembled right out of the box - no frustrating setup required. Made from durable PVC plastic, it can handle being passed around the classroom without breaking. The colors are bright and clear, making it easy to distinguish the different base pairs and sugar-phosphate backbone. It's detailed enough for high school and college levels but simple enough for middle school introductions to DNA structure. The model shows the classic twisted ladder shape perfectly, helping students visualize how genetic information is structured. It's great for explaining replication, transcription, and how DNA codes for proteins. The base keeps it stable on desks or demonstration tables. Whether you're teaching basic biology or advanced genetics, having a physical model makes abstract concepts much more concrete for visual learners. It's one of those classroom tools that teachers use year after year because it effectively demonstrates a fundamental scientific concept. The quality is solid for the price, and it's definitely more durable than paper or foam models. A must-have for any science classroom that covers molecular biology or genetics.
