The ribosome catalyzes the formation of peptide bond between two amino acids. which of the following statements is true?

A) the ribosomal large subunit binds to the mRNA

B) The large and a small subunits of a ribosome once assembled will stay together until the degraded by the proteasome

C) The catalytic site for peptide bond formation is formed primarily from an rRNA

D) The number of rRNA molecules that assemble a ribosome exceeds the number of protein

Expert Solution

Answer:

C) The catalytic site for peptide bond formation is formed primarily from an rRNA

Explanation:

Peptide bond formation is catalyzed at an active site within the large subunit of the ribosome in a region where only rRNA is found. The formation of the peptide bond is catalyzed by peptidyl transferase, an RNA-based enzyme that is integrated into the large ribosomal subunit
