The trip from amino acids to self-replicating cells is a long and mysterious one, but evidently progress is being made.
I am not sure how this new scientific knowlege will supplement the excellent work being done at the prestigious Creation Science Museum.
Take-away for me: cellular genetics is about as mind blowing as quantum physics, to me anyway.

Discovery boosts theory that life on Earth arose from RNA-DNA mix
Newly described chemical reaction could have assembled DNA building blocks before life forms and their enzymes existed.
In a study published in the chemistry journal Angewandte Chemie, they demonstrated that a simple compound called diamidophosphate (DAP), which was plausibly present on Earth before life arose, could have chemically knitted together tiny DNA building blocks called deoxynucleosides into strands of primordial DNA.
The finding is the latest in a series of discoveries, over the past several years, pointing to the possibility that DNA and its close chemical cousin RNA arose together as products of similar chemical reactions, and that the first self-replicating molecules -- the first life forms on Earth -- were mixes of the two.
The finding also nudges the field of origin-of-life chemistry away from the hypothesis that has dominated it in recent decades: The "RNA World" hypothesis posits that the first replicators were RNA-based, and that DNA arose only later as a product of RNA life forms.
