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.
The nitrogenous bases on the two strands of DNA pair up, purine with pyrimidine (A with T, G with C), and are held together by weak hydrogen bonds. Watson and Crick discovered that DNA had two sides, or strands, and that these strands were twisted together like a twisted ladder -- the double helix.
