Deoxyribonucleic acid is a polymer found in all cells that contain information that can be transfered from generation to generation. It also provides means to translate that information into proteins that are needed by the cell in order to function appropriately. It consists of a backbone made up of ribose, a 5 carbon sugar that covalently bonds to the next ribose making a ladder type structure. The nucleic acids, thymine, adenine, guanine and cytosine are the rungs on the ladder and code for the genetic material. The sequence of the nucleic acids provide the code that the cell uses to make the proteins.
