The ribozyme was the first recognized “molecular machine.” Which of the following is TRUE?
Correct Answer: Peptidyl transferases activity
Description: Ribozymes are RNA molecules with catalytic activity. These generally involve transesterification 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 activity). Ref: Weil P. (2011).
