How Do You Make A DNA Model From Pool Noodles?
Creating a model of deoxyribonucleic acid (DNA) using pool noodles can be a helpful learning tool to demonstrate DNA’s properties. DNA is composed of four nucleobases: cytosine, thymine, guanine and adenine. These bases are strung along a phosphodiester backbone to form two complementary strands. The bases of each strand interact with one another through hydrogen bonding, holding the two strands of DNA together. These two strands twist together in a double helical fashion, forming the commonly known double helix of DNA. Understanding the structure of DNA is essential for the study of biology. Because of the complex structure DNA assumes, constructing a model can help students visualize its elaborate nature. Cut two segments of wire using your wire cutters, each segment 2 inches longer than your pool noodles. Also cut 20 segments of wire, each 12 inches long. These will be used to help hold your model together and hold the nucleobases. Run the long wire segments through the hollow cente
