you learned about how antibiotics resistance develops in bacteria in the video from nature. use the information and write a descriptive paragraph about antibiotic resistance. In your discussion include information about how a single bacterium could become resistant to an antibiotic and how that would lead to a population of bacteria becoming resistant. how can this apply to patient who lets concentration of antibiotics in their blood drop? Also include an example of how a bacterium can acquire resistance other than vertical gene transfer.

Your doctor diagnosed your illness as a bacterial sinus infection and prescribed a course of antibiotics. You also gave informed consent to participate in the doctor’s research study on antibiotics. As part of the study you went to the clinic every day to have a sample from the infection taken and analyzed. Before starting on the antibiotics the bacteria were susceptible to the antibiotic; however later in the week after starting the antibiotic treatment the bacteria in your infection were resistant to the antibiotic. Results of DNA analysis of the bacteria causing your infection showed that the resistant bacteria and susceptible bacteria differed only by a gene that encodes the protein target of the antibiotic such that the antibiotic was unable to bind to the target site on the resistant bacterial cells..

Which of the following three hypotheses is most likely? Explain how the results support that hypothesis and what you learned about antibiotic resistance in week 4 topic “Antibiotic Resistance”. What is a possible mechanism for the change in the gene? What are at least three ways previously sensitive bacterial cells acquire the gene for gene for resistance (name and describe them)?

A) You developed a tolerance* for the antibiotic

B) The bacteria infecting you developed a tolerance* for the antibiotic.

C) The bacteria infecting you evolved to be resistant to the antibiotic.

*Tolerance is a nongenetic change in which the response to a specific drug and concentration is weaker after repeated use.

Genetics

=========

Describe a possible sequence of events that couldresult in the transfer of an antibiotic resistance gene from thechromosome of an antibiotic-resistant, F+ bacterium to thechromosome of an antibiotic-sensitive, F- bacterium, thus changingthe recipient cell into a cell that isantibiotic-resistant.

VERY IMPORTANT: Please do not copy-paste from books as I do havemy own book(s), I need an answer from expert who really knows it.If you are unsure, please do not answer as it will only clutterthis thread. Question asked for sequence of events, please try toformulate in a bulleted list.
