True or False:
Despite their simplicity, prokaryotic cells still contain ribosomes.
Correct Answer
True
Explanation
True. Prokaryotic cells do contain ribosomes. However, prokaryotic ribosomes are smaller (70S) than eukaryotic ribosomes (80S). This size difference is clinically important - many antibiotics (such as streptomycin and erythromycin) specifically target prokaryotic ribosomes to kill bacteria without harming the host's eukaryotic cells.
