Indicate whether each of the following antibiotic drug effects is on replication, transcription, or translation. HINT Each answer (replication, transcription, and translation) is used only once for the following: a. Rifampin binds to bacterial RNA polymerase. b. Streptomycin binds bacterial ribosomes, disabling them. c. Quinolone blocks an enzyme that prevents bacterial DNA from unwinding.

1. a)how is it possible for such drugs to selectively kill bacterial cells and not our own cells? b)Provide an example of post-translational regulation of protein activity and explain the advantage of regulating each protein/process at the post-translational level instead of the transcriptional level.
The ribosome is the target for many important antibiotics. These drugs must discriminate between bacterial and eukaryotic ribosomes to achieve drug specificity and toxicity. For the two common antibiotics below, what is their mechanism of action and why are they more toxic to bacteria than eukaryotes? a) Tetracycline b) Erythromycin
Below is the structure of an intercalating agent. By making reference to the structure of the compound, outline the essential structural features for the activity of intercalating drugs acting on DNA.
Various antimicrobial drugs to treat microbial infection have diverse mechanism of action. Consider the following antimicrobial drugs: A. Seconeolitsine, known as DNA topoisomerase I inhibitor in bacteria. (i) Explain briefly how inhibiting DNA topoisomerase I is a good mechanism of action for an antibiotic, include possible molecular machineries being targeted. (ii) What would be an appropriate response if seconeolitsine works well by stating the state of supercoiling in bacteria. (iii) To prove your answer (ii), you test the condition of bacterial DNA by running gel electrophoresis, one has been treated with seconeolitsine (+ sample) and the other one is not (- sample). Explain the position of each + sample and – sample band on the gel in reference to the point of origin (where you load your samples) or how far each DNA sample travel across agarose gel. (iv) Explain why you would expect answer (iii) for each + sample and – sample. B.…
Below, you can see a picture of an antimicrobial drug. Regarding semi-synthetic antimicrobial drug development to try to avoid development of antibiotic resistance, use 1 sentence to address what is the significance/value of the presence of the various R-groups (e.g. R4, R5, R6, etc.)?
Which of the following drugs inhibits protein synthesis through binding to ribosomal 30S subunit: O a. Linezolid O b. Amikacin O c. Ciprofloxacin O d. Azithromycin
Resistance to many penicillins is the result of cell wall mutations in a variety of bacteria. True or false?
Why are bacterial DNA gyrase and topoisomerase good targets for antimicrobial drugs? These enzymes are not necessary for DNA replication. These enzymes are involved in energy production, so targeting them would prevent the bacteria from obtaining necessary energy. These enzymes are different from their eukaryotic counterparts, so the drugs targeting them should not affect the host. These enzymes are responsible for host cell recognition, so targeting them would prevent the host cell from being infected.Flag this QuestionQuestion 10
