Question

Choose the correct option that indicates the enzyme, ribozyme in bacteria that acts as a catalyst.

• A. ( \text{28S rRNA} )
• B. ( \text{5.8S rRNA} )
• C. ( \text{26S rRNA} )
• D. ( \text{23S rRNA} ) \

Answer 1

The Correct Option is D

Ribozymes are RNA molecules that have catalytic activity. In bacteria, the ribosome, which is responsible for protein synthesis, contains a ribozyme. The peptidyl transferase activity, which catalyzes the formation of peptide bonds between amino acids, is carried out by the 23S rRNA component of the large ribosomal subunit. Therefore, 23S rRNA in bacteria acts as a ribozyme.
