Which of the following rRNAs acts as structural RNA as well as ribozyme in bacteria?
Options
- A5S rRNA
- B18S rRNA
- C23S rRNA
- 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.
