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….

These findings emphasize the supraspliceosome as…

Some Surprises A few years ago, the Swedish geneticist Svante Paabo received an unusual fossilized bone fragment from Siberia. He extracted the DNA, sequenced it and realized it was neither human nor Neanderthal. Savante Paabo co-authored this refutation of neo-Darwinian nonsense in 2003.Natural Selection on the Olfactory Receptor Gene Family in Humans and Chimpanzees It links natural selection for energy-dependent codon optimality from the pheromone-controlled physiology…

MicroRNA-mediated RNA epigenetics

RNA Epigenetics DNA isn’t the only decorated nucleic acid in the cell. Modifications to RNA molecules are much more common and are critical for regulating diverse biological processes. Excerpt: …specific alternative splicing types, such as intron retention, exon skipping, and alternative first or last exon usage, were highly correlated with m6A decoration. And silencing the m6A methylating protein METTL3 affected global gene expression and alternative splicing patterns in both human and mouse cells.2 My comment: “Silencing” a protein effects global…
