One hypothesis that has been proposed regarding the origin of life suggests that life evolved from an "rna world" to todays "dna world." considering the properties of rna and dna molecules, which questions would direct an investigation of the most insightful test(s) of this hypothesis?

DNA is the genetic material of all the organism except few viruses. RNA is considered as the first genetic material because it can acts as catalyst. RNA is still present as genetic material in some viruses only.

On the basis of properties DNA and RNA molecule, the question that can be arised whether RNA has the ability to provide the template for the DNA assembly. This enable the formation of a stable molecule like DNA that acts as the genetic material.
