Why do we think that RNA was probably the first self-replicating molecule?
A) it is able to replicate at high temperatures found near deep-sea ocean vents
B) it is much simpler than DNA
C) in laboratory studies researchers have shown that it is able to catalyze its own replication
D) it is able to replicate using carbohydrates rather than proteins

Question

Quizplus · Accepted Answer

In laboratory studies, researchers have demonstrated that RNA is able to catalyze its own replication, which makes it a strong candidate for being the first self-replicating molecule. While options A, B, and D all have some potential relevance to the question, the fact that RNA is able to catalyze its own replication is the most compelling evidence in its favor.
