Bartel's Research Group Showed That an RNA Replicase Ribozyme Could

question 11

Multiple Choice

Bartel's research group showed that an RNA replicase ribozyme could be created by

• A)carefully synthesizing a novel ribozyme monomer by monomer based on the sequence of known ribozymes.
• B)creating large numbers of random RNA segments and testing each one to see if any replicase activity was present.
• C)starting with random components and allowing natural selection to evolve molecules that were better and better at replicating.
• D)examining protein replicases and reverse-engineering an RNA molecule capable of doing the same job.
