True about Ribozyme:: (A) Peptidyl Transferase activity, (B) Cuts DNA at specific site, (C) Participate in DNA Synthesis, (D) GTPase activity
Answer is A. Ans. A. Peptidyl Transferase activity(Ref: Harper 31/e p396)Ribozyme is RNA with catalytic activity.E.g.: SnRNA in Spliceosome-Takes part in splicing of exons and removal of intronsRibonuclease P--Cuts the RNAPeptidyl Transferase: Peptide Bond formation other optionsCuts the DNA at specific site--Restriction EndonucleaseDNA Synthesis--DNA Polymerase
