Carbo - hydrate. Glucose is a common carbohydrate that will show up again and again as we discuss cell chemistry: its formula is C6H12O6. Table sugar, sucrose, is two single sugars bound together: a disaccharide simple sugar. Sugars can be anything from a single sugar molecule up to several bound together.
The two sides of the DNA molecule are Deoxyribose and phosphate these two molecules are what make up the two sides of DNA.
DNA is made up of four bases: adenine (A), cytosine (C), thymine (T), and guanine (G). The order of these bases is called the DNA sequence. Whenever a particular base is present on one side, its complementary base is found on the other side. In the example above, see how the bases always occur in complementary pairs.
