Which is a correct sequence of events in Origin of Life?

I. Formation of Protobionts
II. Formation of organic polymers
III. Formation of organic monomers

OR

1.formation of protobionts
2. synthesis of organic monomers
3.synthesis of organic polymers
4.formation of DNA based genetic systems


Answer both to your best abilities, and please let me know why you think so!


Thank you guys.

Protobiont is an aggregate of organic molecules surrounded by a membrane or like structure. So, organic stuff must come first, and monomers make polymers. There is also a prevailing theory that RNA and proteins existed before DNA.

Thank you, that is what I thought, but some sources are putting polymers before monomers so I was wondering.

here lets clarify this so you don't make that mistake again.

monomer -> mono = one

polymer -> poly = many

therefore monomers must come first because they are smaller.
you can't have humans before the first eukaryote.

Probably because they are using a reaction to produce the monomer subunit. But regarding evolution, polymers are made up of many monomers.
