From a hospital patient afflicted with a mysterious illness, you isolate and culture and then purify DNA from the culture. You find that the DNA sample obtained from the
culture contains two different kinds of DNA: one was labeled as double-stranded
human DNA and the other was labeled as single stranded viral DNA. However, a
mix-up occurred and the labels were accidentally removed from the test tubes. How
can you figure out which test tube contains which DNA, if you only have access to
the nucleotides in each sample? (2 marks)
