This is how to have students create folds in their journals to learn/reinforce the structure of DNA. This will actively involve the students in organizing the information as they describe the 4 different bases & also examine the components of DNA's backbone (phosphate and deoxyribose sugar). In the 2nd half of the activity, they'll summarize how nucleotides, DNA, genes, chromosomes and other terms relate to one another. Notebooking information in this way really seems to help my students
