replication (ˌrɛplɪˈkeɪʃən)
n
1. a reply or response
2. (Law) law (formerly) the plaintiff's reply to a defendant's answer or plea
3. (Biology) biology the production of exact copies of complex molecules, such as DNA molecules, that occurs during growth of living organisms
4. repetition of a procedure, such as a scientific experiment, in order to reduce errors
5. a less common word for replica
So, I'll rephrase my question:
Has Dr. Cech (or anyone else) manufactured, from fundamental atomic precursors, RNA which, after having been manufactured, autonomously produces exact copies of itself from atomic precursors - as required to demonstrate the hypothetical process of evolutionary abiogenesis?
“Has Dr. Cech (or anyone else) manufactured, from fundamental atomic precursors, RNA which, after...”
Just FYI. You’re using terms wrong. It makes you sound like the Bowery Boys.
Molecular precursors would sound OK, but atomic precursors makes no sense in this context.
“Has Dr. Cech (or anyone else) manufactured, from fundamental atomic precursors, RNA which, after having been manufactured, autonomously produces exact copies of itself from atomic precursors - as required to demonstrate the hypothetical process of evolutionary abiogenesis?”
Exact copies? I’m not sure but think, yes. I seem to recall publications describing it, but could be wrong.
Exact copies, though, are not needed for the idea that this RNA mechanism may have contributed to molecular evolution.
Living things do not need reproduce exact copies and don’t.
Our kids aren’t exact copies of us, for example.
