The Development of the Theory of the "RNA World" Resulted

Question

The development of the theory of the "RNA world" resulted from the discovery of
A) archaea.
B) prions.
C) bacteria.
D) ribozymes.
E) endosymbionts.

Accepted Answer

The theory of the "RNA world" proposes that RNA was the first self-replicating molecule and served as the precursor to life as we know it. This theory was developed based on the discovery of ribozymes, which are RNA molecules that are capable of catalyzing chemical reactions. Ribozymes provided evidence that RNA could both store genetic information and carry out enzymatic activities necessary for metabolism, supporting the idea that RNA was the first molecule able to support life.
