Quizplus · Accepted Answer

RNA is widely believed to be the first information storage molecule due to its ability to both store genetic information, like DNA, and catalyze chemical reactions, which is a property of proteins. This dual function supports the RNA world hypothesis, suggesting that life forms based on RNA preceded the current DNA- and protein-based life forms.
