For years, the residents of a small Mexican town complained about the filth from a nearby hog farm, where millions of pigs are raised each year
In 2009, the majority of residents in this town became sick with "swine flu," caused by the H1N1 influenza virus. This virus infects people but is apparently genetically similar to a virus that infects hogs. The virus has since gone on to infect (and, in some cases, kill) people in Mexico City, and has quickly spread around the entire planet. The "swine flu" has been declared a global pandemic. Based on this scenario and your knowledge of genetics, what is a potential technique that could be used to prevent this disease? A) Encourage people not to consume pig products. B) Make recombinant viral and human DNA. C) Genetically engineer flu-resistant pigs. D) Develop a technique for STRs in swine.
