Chapter 26 RNA Metabolism 1. How is RNA synthesized using DNA templates (transcription)? 2. How is newly synthesized primary RNA transcripts further processed to make functional RNA molecules? 3. How is RNA and DNA synthesized using RNa as template (reverse transcription); 4. What is the evolutionary implication of the structural and functional complexity of RNA molecules?
