Although intracellular bacterial infection can be treated by giving an antibiotic that blocks protein synthesis, doesn't affect human cells. Why?

A. Antibiotic molecules can't enter human cells.

B. Antibiotic gets degraded by human cell.

C. Human ribosomes are different from bacterial ribosomes.

D. Human genetic code is different from bacterial genetic code.\r\n
