Polycombic ecological adaptation as a science, not a theory (2)

Evolutionary Constraints in the β-Globin Cluster: The Signature of Purifying Selection at the δ-Globin (HBD) Locus and Its Role in Developmental Gene Regulation Conclusion: … the results here presented indicate that purifying selection is driving not only HBD evolution but also its neighbor pseudogene, HBBP1. In the light of recent advances in the characterization of Polycombic ecological adaptation as a science, not a theory (2)

Biophotonics, glycobiology, quantized biodiversity (2)

From Fertilization to Adult Sexual Behavior (1996) In our section on Molecular epigenetics, we wrote: 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 (Adler and Hajduk, 1994; de Bono, Zarkower, and Hodgkin, 1995; Biophotonics, glycobiology, quantized biodiversity (2)

Energy-dependent RNA methylation (8)

Multiplexing Genetic and Nucleosome Positioning Codes: A Computational Approach Mutation Monte Carlo method (MMC): Excerpt: The mutation moves change the bp sequence but keep the DNA configuration fixed. Both moves change the energy, Eq (1), of the two bp steps involved. My comment: Moves that change energy cost energy. Attributing energy-dependent changes in base pairs Energy-dependent RNA methylation (8)
