E. Ribozymes and the RNA World

Skills to Develop

  • define a ribozyme and describe their known activities;
  • identify, given a reaction mechanism, the types of catalytic mechanisms that occur during ribozyme catalysis;
  • contrast the chemical and physical properties of dsDNA, ssRNA, and proteins and how they may confer on these polymers critical attributes necessary for their biological functions/activities;
  • give reasons that would explain how simple life might have originated using RNA, not DNA and proteins, as both the carrier of genetic information and as biological catalyst.
