Which of the following rRNAs acts as structural RNA as well as ribozyme in bacteria?

Options

  1. A5S rRNA
  2. B18S rRNA
  3. C23S rRNA
  4. D5.8S rRNA

Correct answer

C. 23S rRNA

Step-by-step solution

If two charged tRNAs are close enough the formation of peptide bond between them would be favored energetically. The presence of a catalyst would enhance the rate of peptide bond formation. It is catalysed by enzyme peptidyl transferase (a type of ribozyme — catalytic RNA i.e., 23S rRNA in bacteria and 28S rRNA in eukaryotes). The elongation factors are required in this process.
