You are given two samples of DNA, one from Clostridium perfringens and the other from Mycobacterium tuberculosis. Unfortunately, the labels on the tubes of DNA were accidentally removed, and you do not know which DNA sample belongs to which organism. As you were doing some work with Escherichia coli in the lab, you also have some of its DNA available as well. The %G + %C values for each of the organisms is known (C. perfringens, 27%; M. tuberculosis, 67%; E. coli, 50%). Based upon this information, how could you quickly determine the source of the DNA for your two samples
