Answer:
C) They have similar antibiotic sensitivities to those of bacteria.
Explanation:
- Ribosomes are the site for biological protein synthesis that is composed of macromolecular machine for protein synthesis.
- In archaea they ribosomes comprise of three RNA molecules - 16S, 23S, and 5S.
- The archaeal ribosome is a 70S ribosome that is composed of 50S and 30 S subunits.
- The ribosomal binding site of archaeol ribosome may be similar to that of the bacteria, i.e. the Shine- Dalgarno sequence.
- <em>However, the antibiotic sensitivity of the archaeal ribosome is different than those of bacteria as the r-protein sequence of the archaea are closer to that of eukaryote than the bacteria. </em>
