Experiments with Enzymes Made of RNA Support Which Origin-Of-Life Model

Question

Experiments with enzymes made of RNA support which origin-of-life model?
A) Miller model
B) replicator-first model
C) metabolism-first model
D) DNA world model

Accepted Answer

The replicator-first model is supported by experiments with enzymes made of RNA, as it suggests that life began with the replication of genetic material, which could have been RNA. RNA enzymes (ribozymes) demonstrate that RNA can both store genetic information and catalyze chemical reactions, supporting the idea of an RNA world where RNA performed many of the functions now carried out by proteins and DNA.
