Antibiotics destroy a bacterial infection by disabling ribosomes in the bacteria. Eukarotic cells contain mitochondria that themselves
contain ribosomes while bacterial cells have no organelles and thus
have uncontained ribosomes. How do chemists use this fact to
create antibiotics that can destroy a bacterial infection without
harming human cells?
