Which of the following rRNAs acts as structural RNA as well as ribozyme in bacteria?
23s rRNA present in 50s large subunit of 70s Ribosome. It forms ‘P’ & ‘A’ site of large subunit, that is structural role. While act as peptidyl transferase that is enzymatic role (Ribozyme) of r-RNA.
15s & 18s r-RNA not present in Bacteria while 5 s r-RNA not act as ribozyme.
