After many years of beating my head against the wall trying to get students to understand the difference between a DNA strand and a DNA molecule, the difference between a dATP and an ATP, the difference between a phosphodiester bond and an H-bond, and the importance of H-bonding in transcription, I can say that this kit does all of the above and more!
The materials and methods have been through countless rounds of tweaking and field testing; the best part is that it is now inevitable for students to realize whenever something is wrong and that they need to try again! Each nucleotide measures roughly 4.5 in x 4.5 in, and each kit will easily fit in a quart-sized ziploc bag. I have included 5 tried and true, scaffolded activities as well as pictures of sample models. These kits help my students do SO much better on my exams!
You can go green like I did, and laminate the dickens out of everything, or have students used good old paper and tape. Easy peasy! Just print, cut and go!
