Light, behavior and autophagy, a gender-specific risk factor

|

Structure of photosystem II and substrate binding at room temperature Excerpt: PS II, a membrane-bound multi-subunit pigment protein complex, couples the one-electron photochemistry at the reaction centre with the four-electron redox chemistry of water oxidation at the Mn4CaO5 cluster in the oxygen-evolving complex (OEC). New, detailed snapshots capture photosynthesis at room temperature The living machinery … Light, behavior and autophagy, a gender-specific risk factor

RNA thermometer controls temperature-dependent virulence factor expression in Vibrio cholerae (2014) Excerpt: The stem-loop can be stabilized by strengthening the base pairing between the fourU element and SD sequence through the substitution of G-C base pairs, and this results in an elevated melting temperature (10). Conclusion: RNA thermometers represent a simple yet elegant mechanism for … Base pairs, olfaction and RNA thermometers

See also: Did “Nature” kill Steve Jobs? In my model of biophysically constrained energy-dependent protein folding chemistry and RNA-mediated cell type differentiation, the nutrient-dependent pheromone-controlled physiology of reproduction links the innate immune system to supercoiled DNA, which protects all organized genomes from virus-driven entropy. For comparison to my model, see: Evolution 2016 Videos (Indexed) Youtube … Did “Nature” kill Steve Jobs? (2)

Energy-dependent biodiversity (2)

This will be my next post to the “Creationism” FB group, where biologically uninformed antagonists have been attacking me on all my other posts or my comments on the posts of others. See, for example: In a series of four presentations during three online conferences: “Neuroscience” “Molecular Diagnostics” “Genetics and Genomics,” I linked Einstein’s math … Energy-dependent biodiversity (2)
