(EILL GIVE BRAINLIST AMD LOSTS OF POINTS) DNA always has the same shape. Proteins have thousands of different shapes based on their function. Why are the shapes of DNA and proteins so different? LOOK AT PICTURE ABOVE FOR OPTIONS)

DNA is composed of a sugar-phosphate backbone and nitrogenous bases. In double-stranded DNA, the nitrogenous bases pair up. Adenine pairs with thymine (A-T) and guanine pairs with cytosine (G-C). The shape of DNA resembles that of a spiral staircase. In this double helical shape, the sides of the staircase are formed by strands of deoxyribose sugar and phosphate molecules. The stair steps are formed by the nitrogenous bases.
