How those amino acids became charge which began the proto-chaining of life.
Please explain this strange sentence.
What do you mean when you say "amino acids became charge"?
What is "proto-chaining"? Nobody can answer a question until you frame it in language that makes sense.
I told you already that the transition from an RNA world to DNA is the least difficult question in the study of the origin of life. I can think of much more challenging problems. I think you misread something somewhere that you thought you understood and now you are no longer sure what your question is?
