Question

Which of the following rRNA is intimately involved with the peptidyl transferase activity?

• A. 5S rRNA
• B. 16S rRNA
• C. 28S rRNA
• D. 23S rRNA

Answer 1

Answer:

D. 23S rRNA

• 23S rRNA is intimately involved with the peptidyl transferase activity.

• In this case, the RNA would be acting as a ribozyme.

• The proteins in the ribosome are the structural units and not catalytic units.
