3-D Molecular Designs. Let your students discover the structure of DNA just as Watson and Crick did. This kit incorporates powerful magnets into accurate, 3-D nucleotide representations to make a fun, self-instructive model. As your students correctly join the nucleotides and connect base pairs, they will feel hydrogen bonding between the nucleotides and observe the helical structure of DNA develop. Teacher-developed and field-tested, the classroom kit contains 12 base pairs (6 of each nucleotide).
