Step by step, your students can build a DNA molecule model, and simulate the “unzipping” of hydrogen bonds in the replication of DNA. -- Individual models snap together to form chains and ladders, and can be linked with other models. The double chains also “unzip” for a vivid demonstration of DNA replication. -- Includes: 10 complete color-coded molecular model packets with deoxyribose, phosphate, guanine, thymine, adenine, cytosine and hydrogen bonding pieces; and a teacher’s guide with instructions and reproducible student worksheets. |
