Complexity and more information (comes from a mind, that’s why SETI is looking for information and not random noise) doesn’t argue for a mindless, undirected explanation.(June 8, 2016 at 11:55 pm)snowtracks Wrote: Well, just no other way to say this: Abiogenesis has been dealt a death blow. It turns out the DNA module is not stable as formerly thought but is in need of continuously repair and maintenance which is performed by the cell itself. This means that the DNA and the cell couldn’t have arisen independent of each other; the cell repairs the DNA, and the DNA preserves the cell’s genetics by copying the original (after repairs, if needed) via cell division.
“The reason our genetic material does not disintegrate into complete chemical chaos is that a host of molecular systems continuously monitor and repair DNA. The Nobel Prize in Chemistry 2015 awards three pioneering scientists who have mapped how several of these repair systems function at a detailed molecular level”.* C'est la vie evolution, you been found wanting.

Evolution is not solely about genetics. Ever hear about epigenetics, the study of evolutionary change which isn't based on DNA molecules? We've known for years that DNA is subject to radical mutation (one of the main vectors of genetic evolution, the other being reproductive recombination), and we've also known for years that there are defences against mutation in this way(some genetic, some non genetic). And we also know that some strands of DNA code for proteins in different shape, radically altering their purpose, depending on the stressors affecting a body.
Despite what your peabrain thinks, you are pointing to research which strengthens evolution, not destroys it.
Now, continuing with DNA: the 3 Nobel Laureates discovered after decades of research of mapping at the molecular level that the DNA has 3 molecular systems which constantly monitor the genome and repair any damage.
1. Base Excision Repair - if an amino group is lost and becomes unable to form a base pair, thus breaking the DNA chain an enzyme detects the error, and other enzymes repair it so that the DNA can replicate properly.
2. Nucleotide Excision Repair - through this mechanism, enzymes will cut out (yes cut out), remove, and replace a damaged DNA strand.
3. Mismatch Repair - replication errors often occur as the DNA is copied but enzymes continually detect most of these errors, and other enzymes repair the damaged DNA.*
What this research shows is that for abiogenesis to occur, undirected, random processes must have anticipated the inherent instability of DNA and assembled the cell with the variety of enzymes necessary to prevent the self-destruction of DNA.
