Question

How did the first DNA formed

Answer 1

organic molecules were synthesized in the beginnings of earth and rained down into the oceans. RNA and DNA molecules are just long chains of simple nucleotides that can live in hazardous conditions

Answer 2

Experiments suggest that organic molecules could have been synthesized in the atmosphere of early Earth and rained down into the oceans. RNA and DNA molecules — the genetic material for all life — are just long chains of simple nucleotides. Replicating molecules evolved and began to undergo natural selection.
