Quizplus · Accepted Answer

RNA is believed to have been the first self-replicating molecule as it can both store genetic information and catalyze chemical reactions necessary for its own replication, known as RNA self-replication or RNA world hypothesis. Both proteins and carbohydrates lack the ability to self-replicate, while DNA acts as a template for RNA replication.
