Enzymatic activity of RNA is involved in all of the following EXCEPT: (A) RNA-Aptamer binding to cognate small molecules, (B) Cleavage of nucleic acids, (C) Peptide bond formation, (D) RNA splicing
Answer is A. Ribozymes Present in some RNA molecules Have intrinsic catalytic activity Involve the cleavage of a nucleic acid Two ribozymes are the peptidyl transferase that catalyzes peptide bond formation on the ribosome Involved in the RNA splicing. Aptamers are oligonucleotide or peptide molecules that bind to a specific target molecule.
