  • Describe TWO specific cellular mechanisms through which a bacterium can become resistant to an antibiotic. Please note that this question is NOT about practices or actions we do that contribute to antibiotic resistance in bacteria, such as not taking the entire prescribed dose. Please remember that bacterial cells become resistant or tolerant to antibiotics, NOT human cells, or the human body. *** Perform some research in the college's online library, a microbiology textbook, and other credible scientific sources of information.
  • Explain the concepts of mutation and natural selection as part of the development of antibiotic resistance in bacteria.
  • What are two or three actions that we, as a society, can take to limit or reduce antibiotic resistance in bacteria?

Recent advances in HIV research have led to development of drugs that can prevent the spread of HIV virus in the host. Thinking about the replication cycle of the HIV virus, list a likely drug target encoded by the HIV viral genome and explain in your own words how this new drug might work to stop the spread of HIV virus in the host.
