DNA and Its Replication Model Kit
|
Students build their own eight-rung ladder segments of the DNA molecule. Set contains 12 individually packaged segments for classroom use by 12 students or teams; each segment has 16 nucleotides consisting of pieces representing the nitrogen base (four each of cytosine, thymine, adenine, and guanine), the phosphate group and the deoxyribose sugar group, plus eight hydrogen bonds. The segments can be attached together to make a giant double helix over 2.7 m long, and can be “unzipped” to permit students to replicate their segment. The reusable, color-coded, plastic components (672 pieces) are easily assembled or disassembled. Includes 50 student worksheets/guides and teacher’s instruction manual.
