The First Catalytic and Self-Replication Biological Molecule was Most Likely

Question

The first catalytic and self-replication biological molecule was most likely
A) RNA.
B) DNA.
C) proteins.
D) ATP.

Accepted Answer

RNA is thought to have been the first biological molecule capable of catalyzing chemical reactions and self-replicating. This is supported by the fact that RNA can both store genetic information and catalyze chemical reactions, and can also serve as a template for its own replication.
