The correct option is A II, III, I, IV
The correct sequence of events in the origin of life
II. Synthesis of organic monomers.
III. Synthesis of organic polymers.
I. Formation of protobionts.
IV. Formation of DNA - based genetic systems
The basic idea behind the chemical origin of life is that simple molecules became more complex molecules which eventually allowed the first auto-catalytic self-reproducing molecule to exist. Protobionts are aggregation of organic molecules, surrounded by a membrane, that abiotically coalesces into resemblances of living matter; thought to be the precursors of prokaryotic cells with DNA based genetic systems.
