3. Assume that your results indicate that antibiotics such as tetracycline, streptomycin, and chloramphenicol have a broad spectrum of activity against prokaryotic cells. Why do these antibiotics lack inhibitory activity against eukaryotic cells such as fungi

They cannot bond with the ribosomes of eukaryotic cells

Explanation:

Antibiotics can inhibit the activity of prokaryotic cells but not eukaryotic cells because they cannot bond with the ribosomes of eukaryotes hence unable to harm or stop their formation of protein
