This DNA paper model activity allows students to color, cut and assemble a 20 rung 2-dimensional DNA model. **Students discover the Structure and Function of DNA through Modeling. What are the three parts of a nucleotide? If you lik, Do you need a differentiated DNA structure activity to test your students reading comprehension of the double helix? Push the candies onto the toothpick so that the candies are pressed together in the middle, and you still have a bit of toothpick sticking out on each side, as shown below. Franklin, Rosalind E. and R. G. Gosling. Part one of this assignment has pairs of students create a model of DNA out of licorice, gumdrops and DNA. DNA stands for deoxyribonucleic acid and it is made up of molecules called nucleotides. In DNA, these four chemicals always link together to form pairs: A pairs with T and C pairs with G. In this very specific way, the two complementary strands link together to form DNA: a long molecule that looks a little like a rope ladder, only about 200,000,000 times smaller and twisted. This is an activity that can be modified for middle school science classes or High School Biology classes.
