De novo gene creation: Ignoring the experimental evidence
(click to enlarge)
It’s not entirely clear how olfactory training works on a neurological level.
Olfactory training links the experience-dependent de novo creation of G protein-coupled receptors to supercoiled DNA. Conserved molecular mechanisms link food odors and pheromones from the innate immune system to the physiology of reproduction. Simply put, autophagy protects all organized genomes from virus-driven entropy and all pathology via the de novo creation of odor receptor genes.

The 3D segmentation of high-resolution images provided by SXT reveals an unappreciated interconnectivity between distinct forms of chromatin. The continuous nature of like-chromatin, which is evident even in the nucleolus, supports the existence of non-stereotypic but extensive interactions between different chromosomes, which might have significant regulatory roles in transcription and other nuclear processes.
Natural selection for energy-dependent codon optimality is the obvious link to experience-dependent chromatin remodeling and the de novo creation of species-specific G protein-coupled receptors, which link chemotaxis and phototaxis from the innate immune system to the physiology of reproduction in all living genera. It is obvious to all serious scientists that energy-dependent receptor-mediated biophysically constrained cell type differentiation is the link from angstroms to ecosystems in all living genera. But, in the next sentence, these authors claim (with my emphasis):
Although sequence-specific association of co-regulated genomic loci is appealing, random interactions between loci with shared chromatin properties might be an equally effective way of modulating transcription levels.
No experimental evidence of biologically-based cause and effect supports that ridiculous claim about random interactions. No experimental evidence of biologically-based cause and effect has ever supported similar claims that link anything except the energy-dependent de novo creation of functional protein structures via the modulation of transcription.
Transcription is energy-dependent and biophysically constrained. It links the innate immune system to supercoiled DNA, which protects all organized genomes from virus-driven energy theft and protects all organisms from all pathology via autophagy.

Imaging Technique Reveals Movement of Genetic Material Within Nucleus
Chromatin functions to package DNA so that it can fit inside of a cell, and forms chromosomes. In the video above, take a trip through the nucleus of a cell; in the video below, DNA reorganization in the nucleus a mouse cell is illustrated.
…it had been thought that chromatin existed as a group of disconnected islands, but the latest report indicated that chromatin is compartmentalized into two areas of “crowding” that comprise a continuous network throughout the nucleus.
The continuous network of chromatin distributes energy as information in the context of hydrogen-atom transfer in DNA base pairs. Energy-dependent changes in base pairs link quantized energy from angstroms to ecosystems in all living genera via changes in the microRNA/messenger RNA balance. The ability to image the changes has not been linked from chromatin remodeling to RNA-mediated amino acid substitutions and chromosomal rearrangements, because the detailed sequence of biologically-based cause and effect refutes all neo-Darwinian theories. Natural selection for codon optimality comes first, not natural selection for benefical mutations. There is no such thing as a beneficial mutation.

Detailed 3-D visualizations show an unexpected connectivity in the genetic material in a cell’s nucleus, and provide a new understanding of a cell’s evolving architecture.
What architecture evolves? Does it evolve via mutation-driven evolution? How is that possible?
These unique 3-D reconstructions of mouse olfactory cells, which govern the sense of smell, were obtained using X-ray imaging tools at the Department of Energy’s Lawrence Berkeley National Laboratory (Berkeley Lab). The results could help us understand how patterning and reorganization of DNA-containing material called chromatin in a cell’s nucleus relate to a cell’s specialized function as specific genes are activated or silenced.
The 3-D reconstructions govern the sense of smell via the de novo creation of G protein-coupled receptors in the mouse olfactory cells. The cells do not create or recreate themselves. Organization and reorganization of chromatin is energy-dependent.
“We’re trying to understand how the reorganization of chromatin affects gene expression,” Larabell said.
No you are not. You’re trying to avoid admitting that you got caught with your pants down after having missed all the experimental evidence of biologically-based cause and effect that refutes neo-Darwinian nonsense.
“No one’s been able to study this at the human level yet.” This research will hopefully lead to new insights about diseases and disorders that relate to gene expression. Already, the study’s results are being incorporated into models of cell development.
There is only one model of cell energy-dependent cell type differentiation during the development of all morphological and behavioral phenotypes in species from microbes to humans.
See for example: Nutrient-dependent/pheromone-controlled adaptive evolution: a model
One of the precursors to Alzheimer’s disease, which attacks the brain’s nerve cells, is a loss of smell, so understanding this connection to olfactory nerve cells could perhaps serve as a diagnostic tool and perhaps unlock a deeper understanding of the degenerative disorder.
Who is claiming that this energy-dependent connection to the de novo creation of genes in olfactory nerve cells is not already understood by all serious scientists? Why are they lying about what is already known?
“This work highlights the power of multidisciplinary research,” said Mark Le Gros, associate director of the NCXT and a physicist who was responsible for the design and construction of the X-ray microscope. Le Gros, the lead author in this research, added, “This is an example of work that required a combination of molecular biologists and cell biologists with physicists and computer scientists.”
It highlights the ignorance of theorists. See for example: Search Results for “alzheimer”
For a historical perspective on the ignorance of theorists who are among the molecular biologists and cell biologists with physicists and computer scientists who published a paper that ignored all the accumulated experimental evidence of biologically-based cause and effect, see: Learning from Bacteria about Natural Information Processing
We proposed that, besides “negative entropy,” organisms sense the environment to extract latent embedded information.13 By latent information we refer to data embedded in the environment that, once processed cognitively, initiates change in the organism’s function or behavior. Information induces changes; hence it can be used to generate an internal condensed description (model or usable information) of the environment, which guides the organism’s functioning.

We included a section on molecular epigenetics, and nothing about the facts that we detailed has changed at any level of examination that links energy-dependent changes from angstroms to ecosystems in all living genera.
The Genome, positioning, timings. There are major structural differences between the X and Y chromosomes; e.g., centromeric aiphoid repeats sequences and distribution of heterochromatin (Graves, 1995; Wolfe et al., 1985). These structural differences correlate with sexually dimorphic chromosomal positioning within the nucleus and with male/female differences in replication timing of the active X, the inactive X, and the Y chromosomes, e.g., Boggs and Chinault (1994), Clemson and Lawrence (1996); Hansen, Canfield, and Gartler (1995). Increasingly the structure and timings within the nucleus are realized as contributing to gene expression regulation (Manders, Stap, Strackee, van Driel, and Aten, 1996; Stein, Stein, Lian, van Wijnen, and Montecino, 1996).

Their cited works link energy-dependent chromatin interactions from the determinants of nucleosome organization to G+C content and intrinsic nucleosome occupancy, which is linked to biophysically constrained cell type differentiation via chromosomal inheritance in primary human cells. The terms “promoter elements” and “self-renewal” are used to obfuscate the fact that energy-dependent RNA-mediated amino acid substitutions differentiate all cell types in all living genera in the context of autophagy and polycombic ecological adaptations. The nutrient energy-dependent fixation of the RNA-mediated amino acid substitutions in supercoiled DNA is not mentioned in the context of autophagy, which must be linked to physiology of reproduction. The game of hide the facts about virus-driven energy theft and all pathology continues to be played by experts who do not want anyone to know what they missed when they invented their theories and taught others to believe in them.

The results showed an inverse relation between H1.0 and the division of cancer cells: “As the H1.0 levels fall, the greater the potential of uncontrolled division of cells. In contrast, high levels of the protein prevent this process. We found that the disappearance of protein H1.0 is characteristic of cancer stem cells and it is necessary to maintain the ability of partition and the potential for growth creation.”
Virus-driven energy theft is clearly linked to the disappearance of H1.0 via everything known to serious scientists about autophagy. Energy-dependent RNA-directed DNA methylation stops the proliferation of undifferentiated cell types is all living genera and it links amino acid substitutions from biophysically constrained protein folding chemistry to supercoiled DNA and all biodiversity. Reports of negative supercoiling in bacteria link virus-driven energy theft from the creation of archaea to the transgenerational epigenetic inheritance of Zika virus-damaged DNA via the conserved molecular mechanisms of epigenetic top-down causation that links food odors from pheromones to the physiology of reproduction.
