Group of answer choices
The RNA make up more of the ribosome mass than the protein components.
It contains more RNA subunits than protein subunits.
The proteins play a larger role in the catalytic activity of the ribosome.
The nomenclature of the subunits (ie 50S) refers to the number of protein and RNA subunits

Which one of the following experimental results does not support the hypothesis that the ribosome is a ribozyme?
Group of answer choices
Peptidyl transferase activity is not inactivated by treating the ribosome with detergent.
Peptidyl transferase activity can be inactivated by base changes in the rRNA.
Ribosomes from thermophilic organisms are more stable than from E. coli.
All of the answers support the hypothesis.
There are no proteins observed within 18 angstroms of the peptidyl transferase active site in the crystal structure.

Which of the following best describes the tRNA binding sites of the ribosome?
Group of answer choices
All tRNAs leave the ribosome through the A site.
Each tRNA that associates with the ribosome must first bind in the P site and then moved to the A site.
Only one of the three sites can be occupied by a tRNA molecule at any given time.
The P site contains the tRNA molecule covalently bound to the growing chain of amino acids.
