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

The work of Bartel's group supports the idea of an RNA world, where self-replicating RNA molecules could have been the precursors to life as we know it. This experiment demonstrated that an RNA enzyme (ribozyme) could catalyze the formation of new RNA strands, indicating that RNA molecules could potentially replicate themselves without the need for proteins or DNA. Therefore, the correct choice is C, an RNA world could produce molecules that could self-replicate.
