Our DNA Builder is the perfect way to introduce today’s young learners to the world of genetics! While discovering the basic concepts about the structure of a DNA molecule, budding scientists will hold the base pairs adenine and thymine (AT), and cytosine and guanine (CG) in their hands! Each base is represented by a chunky piece of soft, colorful felt that connects like a puzzle. The double-helix illustration is designed to fit the felt base pairs like the rungs of a DNA ladder. Simply write in the blank where you want your pairs to go, then erase and reuse. The information is minimal, keeping lessons fun and simple — and little scientists engaged!
