Your task is to create a DNA model. You may use any materials you wish when constructing your model, except food items. The model should be at least one foot long and be as realistic as possible. It should show the sugar (shaped correctly), phosphates, bases, the anti-parallel nature of the two strands, the 3′ and 5′ ends (structurally correct), the number of bases per turn, the correct base pairings, the hydrogen bonding between bases (2 or 3 as appropriate), etc… At least part of the model must be twisted in the helix shape.  You also must include a ‘key’ that explains what each item is.  There are examples in class for you to view.
