Question

Quizplus · Accepted Answer

Scientists hypothesize that RNA was the first form of genetic material because RNA can catalyze reactions and store genetic information. This would have allowed for a self-replicating system to form, which is essential for the evolution of life. Additionally, RNA is simpler and more versatile than DNA, which supports the idea that it evolved first. While options B, C, D, and E also describe characteristics of RNA, only option A includes both of the key features that make RNA a likely candidate for the first genetic material.
