Compare and contrast the mechanism of action of two commonly used antibiotics. Include details about which steps of translation are inhibited, and explain how the antibiotic accomplishes this inhibition
What will be an ideal response?
Antibiotics target different aspects of microbe biology to kill microorganisms. Familiar antibiotics such as tetracycline, streptomycin, and chloramphenicol target different stages of microbial translation, as do less familiar antibiotics such as erythromycin, puromycin, and cycloheximide. Each antibiotic contains a different active compound that takes advantage of unique features of bacterial translation to disrupt the production of bacterial proteins while not interfering with the translation of proteins in our cells. That is how the antibiotic selectively kills the bacteria and does not harm our cells.
Answers may vary, but some possible answers are listed below.
