Question

Select the correct statement about archaeal ribosomes.

1) Archaeal ribosomal proteins are more similar to bacterial ribosomal proteins than to eukaryotic ribosomal proteins.
2) Archaeal ribosomes are susceptible to antibiotics, similar to bacterial ribosomes.
3) Archaeal ribosomes have subunits that are identical in shape and chemical components to those of bacteria.
4) The chemical components of archaean ribosomes are more similar to those of eukaryotic ribosomes than to those of bacterial ribosomes.

Answer 1

The chemical components of archaeal ribosomes are more similar to those of eukaryotic ribosomes than to those of bacterial ribosomes.

Step-by-step explanation:

The correct statement about archaeal ribosomes is that the chemical components of archaeal ribosomes are more similar to those of eukaryotic ribosomes than to those of bacterial ribosomes (option 4).

Step-by-step explanation:

Archaeal ribosomes, which are found in organisms called archaea, have a higher similarity in chemical components to eukaryotic ribosomes than to bacterial ribosomes. This indicates that archaea and eukaryotes have a closer evolutionary relationship than archaea and bacteria. In contrast, bacterial ribosomal proteins are more similar to bacterial ribosomal proteins than to eukaryotic ribosomal proteins (option 1). Additionally, archaeal ribosomes are not susceptible to antibiotics in the same way as bacterial ribosomes (option 2). Lastly, the subunits of archaeal ribosomes are not identical in shape and chemical components to those of bacteria (option 3).
