Abiogenesis vs microRNA biogenesis

Summary: The pseudoscientific nonsense about abiogenesis that has been touted by Karo Michaelian and others like him has caused the unnecessary suffering and premature death of millions to billions of people by placing the pathogenic consequences of deregulated miRNAs into the context of ridiculous theories.

Abiogenesis (2017)
Microscopic dissipative structuring and proliferation at the origin of life (Oct 13, 2017)

Some fundamental molecules of life are suggested to have been formed, proliferated, and evolved through photochemical microscopic dissipative structuring and autocatalytic proliferation under the UV-C/UV-B solar environment prevalent at Earth’s surface throughout the Archean. Evidence is given in the numerous salient characteristics of these, including their strong absorption in this spectral region and their rapid non-radiative excited state decay through inherent conical intersections. The examples of the dissipative structuring and dissipative proliferation of the purines and of single strand DNA are given. UV-C and UV-B-induced stationary state isomerizations and tautomerizations are shown to be crucial to the formation of the purines from hydrogen cyanide in an aqueous environment under UV-C light, while UV-C induced phosphorylation of nucleosides and denaturing of double helix RNA and DNA are similarly important to the production and proliferation of single strand DNA. This thermodynamic dissipation perspective provides a physical-chemical foundation for understanding the origin and evolution of life.

The suggestion is ridiculous. No serious scientist would claim that some fundamental molecules of life formed, proliferated, and evolved in the context of thermodynamic dissipation after the UV-C induced phosphorylation of nucleosides and denaturing of double helix RNA and DNA.
The functional structure of supercoiled DNA is energy-dependent.
All serious scientists start with the link from the sun’s anti-entropic virucidal energy on contact with water to the creation of ATP synthase; the creation of microRNAs; the creation of all other enzymes; the creation of all receptors; the creation of all hormones. That’s how serious scientists link microRNA biogenesis to all biophysically constrained food energy-dependent pheromone-controlled morphological and behavioral diversity on Earth.
MicroRNA biogenesis (2018)

The tipping point of 72,000 indexed published works that mention microRNAs was reached on 4/18/18
See: microRNA
Example: Arthropod viruses and small RNAs (2013)

Understanding the role of small RNAs in arthropod host-virus molecular interactions will facilitate manipulation of these pathways for both management of arthropod pests of agricultural and medical importance, and for protection of beneficial arthropods such as honey bees and shrimp. This review highlights recent research on the role of small RNAs in arthropod host-virus interactions with reference to other host-pathogen systems.

Example: MicroRNAs as mediators of insect host-pathogen interactions and immunity (2014)

In this review, we will discuss the latest developments in regards to the role of microRNA in insect host-pathogen interactions and provide some insights into this rapidly developing area of research.

Example: miRNA regulation of innate immunity (2018)

MicroRNAs (miRNAs) are small noncoding RNA and are pivotal posttranscriptional regulators of both innate and adaptive immunity. They act by regulating the expression of multiple immune genes, thus, are the important elements to the complex immune regulatory network. Deregulated expression of specific miRNAs can lead to potential autoimmunity, immune tolerance, hyper-inflammatory phenotype, and cancer initiation and progression. In this review, we discuss the contributory pathways and mechanisms by which several miRNAs influence the development of innate immunity and fine-tune immune response. Moreover, we discuss the consequence of deregulated miRNAs and their pathogenic implications.

The pseudoscientific nonsense touted by Karo Michaelian and others like him has caused the unnecessary suffering and premature death of millions to billions of people by placing the pathogenic consequences of deregulated miRNAs into the context of ridiculous theories.

and Retraction: Oligoarginine peptides slow strand annealing and assist non-enzymatic RNA replication (Nov 23, 2017)
The life’s works of all those who have ever touted their ridiculous claims about abiogenesis can now be placed into the context of the eternal significance of microRNAs. The energy dependent de novo creation of microRNA flanking sequences has repeatedly been linked from the physiology of pheromone-controlled reproduction to biophysically constrained viral latency and sympatric speciation in all living genera.

The synthesis of RNA in isolated thymus nuclei is ATP dependent.

Players take turns placing workers on available organelles within a human cell in order to collect resources (such as Carbohydrates or ATP!) or take actions (such as purchasing Cell Component cards or translating mRNA into Proteins!)

Players use their resources to build Enzymes, Hormones, and Hormone Receptors and also to help detoxify the cell – all of which score health points. The player with the most health points at the end of the game wins!

See for comparison: DNA Denaturing through UV-C Photon Dissipation: A Possible Route to Archean Non-enzymatic Replication (2014)

Many of the fundamental molecules of life, those common to all three domains; bacteria, eukaryote, and archea, including RNA and DNA, amino acids, enzymes, vitamins, cofactors, and protoporphyrins, absorb photons in the UV-C 1. RNA or DNA in complexes with these molecules act as acceptor quenchers, providing the electronically excited pigment donor molecule with an extremely rapid (sub picosecond) non-radiative dexcitation channel, through internal conversion into vibrational energy of the nucleic acid and surrounding water molecules2.

On April 17, 2018, I commented on the ridiculous claim this so-called science journalist made because he blocked me from seeing his tweets a few months ago.
