...Which would have protein synthesis inhibited if they were grown in the presense of chloramphenicol?

Question

The full question and possible answers are:
Chloramphenicol is a drug that inhibits protein synthesis on prokaryotic ribosomes. Which of the following cells (or parts of cells) would have protein synthesis inhibited if they were grown in the presence of chloramphenicol?
A) bacteria
B) chloroplasts
C) mitochondria
D) only A and C are correct
E) A, B, and C are correct

Answer 1

Ahh, but the ribosomes that are found in chloroplasts and mitochondria are both very similar to bacterial ribosomes because both chloroplasts and mitochondria evolved from prokaryotic cells, according to the endosymbiotic theory. So, without doing the research to find out for sure, I'd guess that E would be the best answer.

Answer 2

tetracycline and chloramphenicol the two inhibit protein synthesis in bacteria and are the two bacteriostatic antibiotics. Tetracycline attaches to the 30S subunit of the bacterial ribisime complicated and inhibits attachment of the subsequent amino acid. Chloramphenicol attaches to the 50S subunit and impairs substrate binding.

Answer 3

I would say A is the correct answer

bacteria are prokaryotes and contain ribosomes

mitochondria are only found in eukaryotic cells

chloroplasts are only found eukaryotes too.
