We are asked for three differences between DNA and RNA.  Two differences are structural, the other is functional.  One difference is that RNA contains a hydroxyl group on the 2 position of the ribose sugar while DNA does not (the D in DNA stands for deoxy).  Another difference is that DNA uses the nitrogenous base thymine as one of the four bases while RNA substitutes this with uracil.  Finally, both nucleic acids serve a difference function.  DNA contains all of the hereditary information for an organism.  It is a storage medium.  RNA is utilized in various forms for the synthesis of proteins in a cell.  It is less of a storage medium and more of a functional device.
