De novo creation of olfactory receptor genes

terrarium eco system

Large-scale transcriptional profiling of chemosensory neurons identifies receptor-ligand pairs in vivo Reported as:  Deciphering the olfactory receptor code Excerpt: Its applications, countless, extend for example to the domain of chemicals able to trigger predetermined behaviors in mammals or in insects,…

RNA-mediated.com (topic descriptions)

The life cycle of an mRNA in a eukaryotic cell RNA is transcribed in the nucleus processing, it is transported to the cytoplasm and translated by the ribosome. Finally the mRNA is degraded

Another companion domain has been added to the ScentofEros.com; Pheromones.com, PerfumingtheMind.com collection Intro to topics/catagories at RNA-mediated.com Information that links physics, chemistry, and molecular epigenetics from ecological variation to ecological adaptations via RNA-mediated events, such as the de novo creation…

Let there be anti-entropic light (1)

terrarium eco system

Summary: Light-induced amino acid substitutions link cell type differentiation in plants to nutrient-dependent pheromone-controlled reproduction in animals via the biophysically constrained chemistry of protein folding. Protein folding is perturbed by mutations that limit the ability of organisms to adapt to…

An epigenetic trap (the prequel)

terrarium eco system

See also: An epigenetic trap (the sequel) Excerpt: “Support for the link from one epigenetic trap to cell type differentiation was included in the molecular epigenetics section of our 1996 review, which detailed how RNA-mediated chromatin remodeling occurs.” My comment:…

The biologically-based origin of the mammalian placenta (2)

The past is not the key to the present

See also: The biologically-based origin of the mammalian placenta I’ll preface this follow-up on the origins of the mammalian placenta with comments that attest to foolishness of theoretical physicists who try to link Big Bang cosmology to neo-Darwinian theories about…

Quantum Superpositions: let there be light

Physics

Ideal Negative Measurements in Quantum Walks Disprove Theories Based on Classical Trajectories Reported as: Atoms can be in two places at the same time Excerpt: “This is not yet a proof that quantum mechanics hold for large objects,” cautions Alberti….

Environment epigenetically shapes the immune system

human-evolution

Environment, more than genetics, shapes immune system 1) –with my emphasis Re: “There’s nothing here that is revolutionary or requires rethinking of our assumptions about how the immune system functions…” My comment: They removed assumptions about cell type differentiation by…
