[{'content': 'Which of the following statement is TRUE about Ribozyme? \nSelect and explain. \nA. Pepitdyl transferase activity, B. Cut DNA at specific site, C. Paicipate in DNA synthesis, D. GTPase', 'role': 'user'}, {'content': "Answer: A \nExplanation: Ribozymes are RNA molecules with catalytic activity. These generally involve trans esterification reactions, and most are concerned with RNA metabolism (splicing and endoribonuclease). Recently, a rRNA component has been implicated in hydrolyzing an aminoacyl ester and thus to play a central role in peptide bond function (peptidyl transferases.) Ref: Weil P. (2011). Chapter 36.
