Hard Science vs the neo-Darwinian “magic box”

Summary: Identical nucleotide sequences link energy-dependent changes in binding sites to different amino acids in different proteins. The binding sites are conserved in the orthologous mammalian genes. The in vivo structure of biological membranes and evidence for lipid domains Scientists investigate how the sense of smell works in bacteria Biogenic non-crystalline U(IV) revealed as major Hard Science vs the neo-Darwinian “magic box”

Energy-dependent epigenetic translation to mRNA stability (6)

See: Energy-dependent epigenetic translation to mRNA stability (5) Five energy-dependent amino acid substitutions are linked to differences in RNA content and biodiversity in 4 mammalian species. Excerpt: Species- and tissue-specific variation in mt-tRNA incorporation into the mt-LSU was analyzed….  Analysis of porcine dermal fibroblasts (C), human osteosarcoma 143B cells (D), bovine cardiac tissue (E), and Energy-dependent epigenetic translation to mRNA stability (6)

Energy-dependent epigenetic translation to mRNA stability (5)

Energy-dependent epigenetic translation to mRNA stability (4) From Fertilization to Adult Sexual Behavior Small intranuclear proteins also participate in generating alternative splicing techniques of pre-mRNA and, by this mechanism, contribute to sexual differentiation in at least two species, Drosophila melanogaster and Caenorhabditis elegans….

Energy as information and constrained endogenous RNA interference (4)

Premise: Sunlight is the energy as information that is required to link endogenous RNA interference to healthy longevity Counter claim:  The Quantum Thermodynamics Revolution: Information theory Understanding entropy as a subjective measure allows the universe as a whole to evolve without ever losing information. Precision Medicine virtual conference, Feburary 22-23, 2017 Title: Energy as information Energy as information and constrained endogenous RNA interference (4)

Viruses in pathogenic variants disrupt alternative splicings

Pathogenic variants that alter protein code often disrupt splicing Approximately 10% of exonic mutations altered splicing, mostly by disrupting multiple stages of spliceosome assembly. We present a large-scale characterization of exonic splicing mutations using a new technology that facilitates variant classification and keeps pace with variant discovery. Assay of nearly 5,000 mutations reveals roots of Viruses in pathogenic variants disrupt alternative splicings

Epigenetically-effected nucleosome repositioning sheds Dobzhansky’s light on evolution

Crystal structure of the overlapping dinucleosome composed of hexasome and octasome My summary: Nucleosomes are dynamic entities that are repositioned by energy-dependent links from sunlight to ATP and RNA biosynthesis that act on DNA during the chromatin remodeling, which is biophysically constrained by the pheromone-controlled physiology of reproduction during the transgenerational epigenetic inheritance of all Epigenetically-effected nucleosome repositioning sheds Dobzhansky’s light on evolution

Synthetic RNA-based switches

Synthetic RNA-based switches for mammalian gene expression control Current Opinion in Biotechnology, Volume 48, December 2017, Pages 54–60 If you wait until December, 2017 to see this article in print, you will probably be among the last of those to have missed a two decades-old paradigm shift. The fact that these researchers created synthetic RNA-based Synthetic RNA-based switches

Functionally interdependent editing and methylation

Editing and methylation at a single site by functionally interdependent activities …cytosine 32 in the anticodon loop of Trypanosoma brucei tRNAThr is methylated to 3-methylcytosine (m3C) as a pre-requisite for C-to-U deamination. Formation of m3C in vitro requires the presence of both the T. brucei m3C methyltransferase TRM140 and the deaminase ADAT2/3. Once formed, m3C Functionally interdependent editing and methylation

Light-activated feedback loops vs self-organization of ecosystems

John Lieff has been trying to update his ridiculous misrepresentations of biologically-based cause and effect to match the accurate representations we made in a section on molecular epigenetics in our 1996 Hormones and Behavior review. From Fertilization to Adult Sexual Behavior Nothing can stop him, but this will provide the next source for material that Light-activated feedback loops vs self-organization of ecosystems
