Use this DNA model to build one (1) biologically accurate DNA model. Rediscover DNA with this larger-than-life model! It's easy — just attach the nucleotide bases to the backbone, pair the DNA strands, then twist them to form the familiar double helix. Just like a puzzle — and just as in nature — this DNA model fits together only one way: adenine (A) pairs with thymine (T) and guanine (G) pairs with cytosine (C) on the sugar phosphate backbones. Use this biologically accurate foam DNA model, over 2 feet tall, in a number of fun and educational ways: Show the right-handed double helical structure of DNA; Incorporate STEM concepts through the use of modeling; Illustrate the base-pair relationship between purines and pyrimidines; Engage your students with this friendly, interactive model. The DNA model includes everything you need to build one (1) biologically accurate DNA model, an instruction sheet, and 10 fun facts about DNA.
