I'm stuck on these Questions
Â
1. How are natural selection and microevolution illustrated in this scenario? Identify the genetic basis for HIV evolutionary change, the selective pressure, and the resulting adaptation. What happens to mutants that are able to escape detection by the immune system?Â
Â
2.) Describe how mutations could lead to drug resistance in the RT enzyme. Include physical, molecular, and biochemical reasons.
Â
4. Why is STI considered a scientifically controversial strategy? Suggest three biological reasons why STI could be advantageous. Predict what will happen to the virus over time if patients are then allowed to resume their HAART therapy after STI. Propose situations in which the STI approach may not be recommended or effective in some HIV-positive people. How would a physician be able to tell if STI is working?
Â
5. Predict what will happen to infection rates over time if drug resistant forms of HIV are allowed to spread through the population. What conditions might slow the spread of drug resistant strains?
