Prokaryotic ribosomes differ from those present in eukaryotic cytosol. Because of this, which of the following is correct?
A)Some selective antibiotics can block protein synthesis of bacteria without effects on protein synthesis in the eukaryotic host.
B)Eukaryotes did not evolve from prokaryotes.
C)Translation can occur at the same time as transcription in eukaryotes but not in prokaryotes.
D)Some antibiotics can block the synthesis of peptidoglycan in the walls of bacteria.
E)Prokaryotes are able to use a much greater variety of molecules as food sources than can eukaryotes.

Question

Selective antibiotics can block protein synthesis in bacteria without affecting protein synthesis in the eukaryotic host because bacterial ribosomes are structurally different from eukaryotic ribosomes. This difference allows for the selective targeting of bacterial protein synthesis without harming the host.
