DNA Model Set and Stand

Build and Understand the Structure of DNAThe Mega Molecules DNA Model Set offers a hands-on, inquiry-based approach to learning the structure and function of DNA. Students actively construct a model of this essential biological molecule, reinforcing how genetic information is stored and transmitted. Through assembly, learners explore the fundamental components of DNA and how they fit together to form the double helix. Construct Nucleotides and Base SequencesStudents begin by assembling individual nucleotides, each composed of a phosphate group, a deoxyribose sugar, and one of the four nitrogenous bases: adenine, thymine, cytosine, or guanine. These are joined together with flexible connectors representing covalent bonds to create a single DNA strand based on a provided gene sequence. This step builds understanding of molecular structure and sequence specificity. Build the Complementary StrandOnce the first strand is complete, students apply base-pairing rules—A with T, and C with G—to
