What characteristic distinguishes nucleic acids from proteins making them better candidates to have been the hereditary molecule in the first protocells?     A single molecule contains the information needed to make a duplicate copy.     They are complex enough to carry instructions to build a cell.     They have catalytic activity.     They can compartmentalize.     Their monomers form abiotically.
