Some antibiotics can block protein synthesis in bacteria without affecting the cells of the eukaryotic host. This is possible because: bacteria can use a much greater variety of food sources than can eukaryotes translation occurs in the nucleus while transcription takes place in the cytoplasm bacterial ribosomes are different than eukaryotic ribosomes in protein content and RNA content ribosomes are not found in prokaryotes
