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.

Answer 1

d. human genetic code is different from bacterial genetic code.

Answer 2

Answer:

Although "intracellular bacterial infection" can be treated by giving an antibiotic that "blocks protein synthesis", it doesn’t affect "human cells". This is because, the "genetic code" in human beings differ from the genetic code of a bacterium. Thus the antibiotic that blocks protein synthesis in a bacterium has no visible effect on human beings. Thus, the correct answer is that the human genetic code is different from bacterial genetic code.
