Problem 8: Identification of a macromolecule

The structure shown in the diagram is an example of:
A. a polysaccharide. B. DNA. The alternating sugar-phosphate backbone tells us that this is either DNA or RNA. The characteristic identifying features of DNA, but not RNA, include the absence of a hydroxyl group at the 2'-position on the sugar and the presence of the T base. C. RNA. D. a protein. E. a lipid.
