How Do You Make A Double Helix DNA Structure?
DNA (deoxyribonucleic acid) is the blueprint or building block of all genetic material. The structure of DNA molecules looks like a ladder that has been twisted into a curving staircase. The sides (backbone) are nucleotides made of sugars and phosphate. The “steps” of the ladder consist of four types of molecules called bases. A model of this structure can be made of almost anything (toothpicks, recycled cans, LEGOs, candy, etc.). The idea is the same no matter what material you use. You can also purchase ready-to-make kits. Cut the licorice into 1-inch pieces. Alternating red and black, string the licorice together into two strands the same length. Separate four different colors of marshmallows. Slide two marshmallows onto each toothpick (at least 20 toothpicks).The bases work as pairs so make sure to keep your color pairs together (e.g., red and yellow together and blue and green together). Connect the ends of the toothpicks to the licorice sides. Connect one toothpick for each segme
