The work of Bartel's group on the ribozyme RNA replicase supports which conclusion?
A)An RNA world could produce molecules that could self-replicate.
B)Natural selection does not work unless humans are present to help it.
C)DNA must have come before RNA.
D)Life cannot come from nonlife.

Question

Quizplus · Accepted Answer

Bartel's group demonstrated that a ribozyme RNA replicase could catalyze the replication of RNA, supporting the idea of an RNA world where self-replicating RNA molecules could have been the precursors to life as we know it. This discovery does not support options B, C, or D.
