How Do You Make A DNA Model?
DNA is the basic building block of every living thing. DNA is so important that every school requires its students to understand how it works. Making models to demonstrate the process is a common biology lab project. This model makes the process easy to understand. Step 1 Choose a handful of toothpicks and 4 different colors of gum drops. Your finished model will look like a twisting ladder. The licorice uprights of the ladder will depict the sugar/phosphate of the DNA. The gum drop rungs of the ladder depict the nitrogen-containing bases. Step 2 Draw a legend to help you remember which colors of gum drops represent which base. You will need a color for Adenine, Thymine, Guanine and Cytosine bases. The pairing is: Adenine with Thymine and Guanine with Cytosine. The pairs complement each other. Step 3 Use a toothpick to attach a gum drop to a licorice stick. Step 4 Push the gum drops close to the licorice stick, leaving enough room on the side to add a second DNA strand (licorice stick)
