Which of the Following is Not True About Archaeal Ribosomes

Question

Which of the following is not true about archaeal ribosomes?
A)They are 70S like bacterial ribosomes.
B)They may possess ribosome binding sites homologous to bacterial Shine-Dalgarno sequences.
C)They have similar antibiotic sensitivities to those of bacteria.
D)All of these are true about archaeal ribosomes.

Accepted Answer

Archaeal ribosomes are known to be 70S like bacterial ribosomes, and they may possess ribosome binding sites homologous to bacterial Shine-Dalgarno sequences. However, their antibiotic sensitivities are not identical to those of bacteria. Some antibiotics may affect archaeal ribosomes differently from bacterial ribosomes.
