The radical pair mechanism and the avian chemical compass: Quantum coherence and entanglement


Radical pairs are usually produced as short-lived intermediates through decomposition, electron transfer, or hydrogen transfer reactions from singlet or triplet excited states.

My comment: The radical pair mechanism appears to be another link from nutrient energy-dependent hydrogen-atom transfer in DNA base pairs to ecological speciation. However, the hydrogen-atom transfer in DNA base pairs mechanism seems to have gone unrecognized despite this report.

The radical pair mechanism (RPM) is considered as a plausible mechanism for explaining the biological effects of weak MFs [7]. Based on quantum mechanics, the RPM predicts MF effects on the lifetime of radical pairs. This mechanism is theoretically well known [7,33–34] and has been experimentally demonstrated in chemical systems [35]. In biology, the RPM seems to be involved in animal navigation, through detection of the geomagnetic field in specific magneto-sensitive molecules [35].

My comment: Disorienting epigenetic effects of weak magnetic fields (MFs) that are known in theory could be linked from atoms to ecosystems via what is known about the biophysically constrained nutrient energy-dependent physiology of reproduction and ecological speciation in white-throated sparrows and other model organisms. However, the advantage of the white-throated sparrow model is the link from atoms to ecosystems that appears to be manifested in different morphological phenotypes and different behavioral phenotypes in the same species.

My comment: Taken together, it is less likely that serious scientists will miss the link from atoms to ecosystems via chromosomal rearrangements and biodiversity in birds that links their biodiversity to the biodiversity of microbes via RNA-mediated amino acid substitutions linked to chromosomal rearrangements. The conserved molecular mechanisms of quantum physics link nutrient energy-dependent hydrogen-atom transfer in DNA base pairs across all living genera via their physiology of reproduction.

10.7.2. RNA repair/editing system
RNA editing refers to molecular modifications of nucleotides of RNA through chemical changes in the base makeup of the molecule. Such changes appear to be present in all three domains of life, and involve both coding, mRNA, and non-coding, tRNA and mRNA, types of small or microRNA. RNA editing occurs in the cell nucleus and the cytosol, as well as in mitochondria and is mediated by a complex repair system comprising many species of small RNA (guide RNA) and large protein complexes known as the editosomes. The pathways of RNA editing include many diverse processes: nucleoside base modifications such as cytidine (C) to uridine (U) and adenosine (A) to inosine (I) deaminations, as well as non-templated insertions of nucleotide. RNA editing in mRNAs effectively alters the amino acid sequence of the encoded protein so that it differs from that predicted by the genomic DNA sequence. Though mRNA editing is used in many instances to allow for synthesis by the cell of more than one protein from the same mRNA transcript, e.g. synthesis of both apolipoprotein B-100 and apolipoprotein B-48 from the same mRNA in liver cells, it can also be used to repair missense or termination mutations of the molecule which can have deleterious effects on the synthesized protein. Specific endonucleases and ligases for double stranded species of RNA have been defined in many prokaryotes and it might be just a matter of time before defining their functional counterparts in eukaryotes and human cells.

My comment: RNA-mediated DNA repair is nutrient energy-dependent and it is linked from ecological variation to ecological adaptation via the physiology of reproduction in all living genera. The physiology of reproduction links atoms to ecosystems via nutrient energy-dependent hydrogen-atom transfer in DNA base pairs.
If you do not understand that fact, you cannot understand how cell type differentiation occurs in the context of healthy longevity compared to pathology. Neo-Darwinists, for example, link mutations to healthy longevity via evolution.
