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

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.
