>>14358167probably very feasible , I'd even say its goes more backward than that , if you follow the formula of life backward you probably reach the origin point , meaning if DNA leads to RNA and RNA leads to protein and protein leads to various components that can defy natural chemical limits to propagate the cycle like enzymes , the origin lies somewhere in basic macromolecules creating some self sustaining loop to produce proteins and precursors of enzymes that go back and help produce more of the components that come to together to build them and so on until you reach some ancient predecessor of the more complex RNA and later way more complex DNA
