In the article “Molecular evidence of HIV-1 transmission in a criminal case” by Metzker et al. (2002), how were the evolutionary properties of the HIV virus used to determine whether or not the victim (the nurse) was injected by the suspect (the doctor) with HIV+ blood from one of the doctor’s patients. Describe the experimental design for testing the hypothesis that the nurse was infected by the patient’s HIV+ blood rather than the other way around.
