Question

According to evolution where did DNA come from?

Answer 1

Evolution of DNA

1. DNA(Deoxyribonucleic acid) is the hereditary material that is said to have appeared from RNA(Ribonucleic acid).
2. As per evolution, macromolecules were synthesized abiotically in the primitive oceans.
3. A large number of organic compounds like methane, hydrogen, ammonia, carbide, cyanide, nitride, etc., were already available in the ocean.
4. These organic compounds combine to form sugar, urines, fatty acid, fatty acid, etc.
5. The requirement of energy for the chemical reaction was extracted by U.V rays, cosmic rays, and volcanic eruptions.
6. So sugar, nitrogenous bases, and phosphates were combined and formed nucleotides which later polymerized into RNA.
7. RNA polymerases were able to produce single-stranded complementary DNA. This further got stabilized into double-stranded structures.
