Final answer:
Tetracycline and chloramphenicol are antibiotics that work by affecting the process of protein synthesis in bacteria. Tetracycline blocks tRNA binding to the ribosome, while chloramphenicol blocks peptidyl transfer, inhibiting the growth of the protein chain.
Step-by-step explanation:
Many antibiotics, such as tetracycline and chloramphenicol, work by affecting the process of protein synthesis in bacteria. Tetracycline blocks the A site on the bacterial ribosome, preventing tRNA binding and inhibiting protein synthesis. Chloramphenicol blocks peptidyl transfer, which is necessary for the growth of the protein chain. These antibiotics specifically target bacterial protein synthesis and do not affect protein synthesis in humans.
