Energy-dependent physical and biophysical constraints (9)

Summary: Energy determines genome compaction because activity in the nucleus is energy-dependent. Chromatin chains link energy-dependent changes in base pairs from single nucleotide polymorphisms to fixation of RNA-mediated amino acid substitutions in organized genomes via the physiology of pheromone-controlled reproduction. It’s all about the base. Energy-dependent physical and biophysical constraints (8) ChromEMT: Visualizing 3D chromatin […]

Functionally interdependent editing and methylation

Editing and methylation at a single site by functionally interdependent activities …cytosine 32 in the anticodon loop of Trypanosoma brucei tRNAThr is methylated to 3-methylcytosine (m3C) as a pre-requisite for C-to-U deamination. Formation of m3C in vitro requires the presence of both the T. brucei m3C methyltransferase TRM140 and the deaminase ADAT2/3. Once formed, m3C […]

Light-activated feedback loops vs self-organization of ecosystems

John Lieff has been trying to update his ridiculous misrepresentations of biologically-based cause and effect to match the accurate representations we made in a section on molecular epigenetics in our 1996 Hormones and Behavior review. From Fertilization to Adult Sexual Behavior Nothing can stop him, but this will provide the next source for material that […]

Sal Giardina: apologetics revisited

Feierman: Variation is not nutrient availability and the something that is doing the selecting is not the individual organism. A […]

Theistic evolutionists fight back and lose

A giant neuron found wrapped around entire mouse brain Yuste and Eberwine would like to see 3D reconstructions of individual neurons compared to analyses of the genes expressed in those neurons. This may offer clues as to the type and function of each cell. The nutrient energy-dependent structure and function of all cell types in […]
