Shall he that contendeth with the Almighty instruct him? Job 40:2
"Knoll is admitting here that no one can yet make the nucleotides which are the building blocks of RNA and DNA.
Even if a scientist had all the right parts to start out with he could not put them together to make even the nucleotide building blocks of RNA, let alone RNA itself.
Knoll’s quote continues:
“There is still another difficulty.
Nucleotides are chiral molecules, which is to say that they come in two forms which are mirror images of each other—like your hands. --RNA can be built from right-handed or left-handed molecules, but mixed chains won’t grow.
Q: How then could RNA—which in cells consists exclusively of right handed nucleotides—have emerged from a fifty-fifty mixture of left- and right-handed building blocks?
Again, no one knows.
The problems are so difficult that many researchers have given up on the idea that RNA was the primordial molecule of life.”
