As A and T always pair up and C and G also always go together, one strand is enough to recreate the molecule. Even before the structure of DNA was solved, studies indicated that the genetic material must have the following properties: be able to store information; be faithfully replicated and be passed on from generation to generation; and allow for changes, and thus evolution, to occur.
