WebA Pre-RNA World Probably Older the RNA Our. Although RNA appears well suited to form the basis for a self-replicating set of biochemical spent, it is unlikely so RNA was the first artist of mold to do so. From a purity dry standpoint, e a difficult to imagine how longer RNA molecules could be formed original by purely nonenzymatic means. WebThis ability probably first evolved in the form of an RNA self-replicator — an RNA molecule that could copy itself. Many biologists hypothesize that this step led to an “RNA world” in which RNA did many jobs, storing genetic information, copying itself, and performing basic metabolic functions.
