Detailed explanation-1: -The first genetic material was RNA as there is evidence that suggests essential life processes evolved around and from RNA such as metabolism, translation, splicing, etc. RNA also used to act as a catalyst and a genetic material in living system in important biochemical reactions.
Detailed explanation-2: -According to the authors of the study, these results suggest that the earliest DNA molecules could have appeared in parallel with RNA-some 4 billion years ago. This would mean that DNA molecules emerged around 400 million years earlier than previously thought.
Detailed explanation-3: -RNA: Ribosomal nucleic acid is the first genetic material to be discovered.
Detailed explanation-4: -RNA is the first genetic material in cells because: RNA is capable of both storing genetic information and catalyzing chemical reactions. Essential life processes like metabolism, translation, splicing, etc. evolved around RNA.
Detailed explanation-5: -Complete answer: RNA was the first genetic material. Life processes have evolved around RNA. It used to act as genetic material as well as a catalyst but RNA being was reactive and unstable.
