Cell types, SNVs, CNVs, and chromosomes

See also: A “new” code enables ecological adaptation For comparison, see: Genome-Wide Detection of Single-Nucleotide and Copy-Number Variations of a Single Human Cell Excerpt: Single-molecule and single-cell studies reveal behaviors that are hidden in bulk measurements (1, 2). In a human cell, the genetic information is encoded in 46 chromosomes. The variations occurring in these chromosomes, such as single-nucleotide variations (SNVs) and copy-number variations (CNVs) (3), are the driving forces in biological processes such as evolution and cancer. Such dynamic…

Anti-entropic containment of energy: symbiosis 1.0

Scientists explore the origins of energy in chemical reactions using experimental quantum chemistry Excerpt: One thing that all chemical reactions have in common—whether they are the reactions that take place inside a battery, the metabolic reactions inside a living organism, or the combustion reactions that cause an explosion—is that they all involve some kind of change in energy. My comment: Therein lies the problem with attempts by pseudosceintists to link nutrient energy from ecological variation to epigenetically-effected ecological adaptation, which…

The “great filter” is an epigenetic trap

The great filter The silence of universe seems ominous. Was Earth lucky? Thanks to George Ellis​ for alerting others to this. Excerpt: Nick Lane in his magnificent new book The Vital Question thinks that a peculiar feature of all earthly life — that it traps energy in the form of protons pumped across membranes… Excerpt 2) Next, after a couple of billion years, creatures bigger than microbes emerged, once (Nick Lane argues) an energy-per-gene limit was breached by the invention…

Epimutation.com: a domain of confusion

See: Epimutation.com Currently, there is no content. When content is added, it will almost undoubtedly further the cause of confusion that evolutionary theorists must use in attempts to prevent serious scientists from Combating Evolution to Fight Disease. Serious scientists use what is currently known about biologically-based cause and effect. Prepare yourself for more pseudoscientific nonsense about epimutations. Until then, see this: Researchers investigate effect of environmental epigenetics on disease and evolution Excerpt 1) …environmental factors are having an underappreciated effect…

Viruses, amino acids, and somatic cell types (2)

Quantitative and functional interrogation of parent-of-origin allelic expression biases in the brain Excerpt: The RNA-seq data enabled us to detect a positive correlation between developmental changes in the magnitude of parental biases and overall gene expression for most imprinted genes. Conclusion: At the level of the organism, our data uncover how paternal and maternal alleles of Bcl-x make vastly different contributions to brain development, a result that has profound implications for the analysis of parentally-inherited polymorphisms in human health. Reported…

Domestication via a single amino acid substitution

Evidence That the Origin of Naked Kernels During Maize Domestication Was Caused by a Single Amino Acid Substitution in tga1 Excerpt: “Our molecular and genetic analyses of tga1 show how a simple amino acid change can alter protein function and thereby drive the evolution of a new phenotypic state.” Reported as: Study shows how a kernel got naked and corn became king Excerpt: The answer often lies in mutations, the currency of evolution. Sometimes single letters are changed in the…

Becoming biologically informed (3)

See also: Becoming biologically informed and Becoming biologically informed (2) Now available for free: New Perspectives on microRNA in Disease and Therapy (July 22, 2015) My comments: Perhaps someone will correct me if I am wrong. The microRNAs do not appear to participate in a direct response to viruses. But, over long periods of time they may fine-tune the microRNA/messenger RNA balance in the organized genomes of all living genera.  If so, the changes are manifested in morphology and in…

Easy editing: Reinventing our RNA world

Easy DNA Editing Will Remake the World. Buckle Up. Excerpt: Most present-day animals and plants defend themselves against viruses with structures made out of RNA. My comment: RNA-mediated gene duplication and fixation of  RNA-mediated amino acid substitutions in the context of the nutrient-dependent physiology of learning, memory, and reproduction links the biophysically constrained chemistry of cell type differentiation in all genera via conserved molecular mechanisms. That fact was integrated into the science fiction novel Blood Music by Greg Bear, who…

Riding the wrong direction

Riding the Evolution Paradigm Shift With Eugene Koonin Excerpt: The entire evolution of the microbial world and the virus world, and the interaction between microbes and viruses and other life forms have been left out of the Modern Synthesis… Excerpt: [T]he entire ideology of personalized medicine should be taken with many grains of salt. My comment: Personalized medicine links the conserved molecular mechanisms of biologically-based cause and effect from nutrient-dependent RNA-mediated gene duplication to RNA-mediated amino acid substitutions, which differentiate…

MicroRNA controlled growth and brain development

Navigable networks as Nash equilibria of navigation games Nature Communications | Article  Open Excerpt: Here we show that the ideal maximally navigable networks do share some basic structural properties with the Internet, E.coli metabolic network, English word network, US airport network, the Hungarian road network and a structural network of the human brain. Reported as: Researchers find the organization of the human brain to be nearly ideal Excerpt: “An optimal network in the brain would have the smallest number of…
