From a hospital patient affected with a mysterious illness, cells were isolated, cultured and purified its DNA. The DNA samples obtained from the cultures contain 2 different DNA, a double strand and a single strand viral DNA. The base composition of the 2 purified DNA samples were the following result: Which test tube is the human DNA present? Justify your answer.
