Bobo Feng et al. The main stabilizer of the DNA double helix is not the base-pair hydrogen bonds but coin-pile stacking of base pairs, whose hydrophobic cohesion, requiring abundant water, indirectly makes the DNA interior dry so that hydrogen bonds can exert full recognition power. We report that certain semihydrophobic agents depress the stacking energy […]
A New Insight Into How DNA Is Held Together

Chalmers University of Technology DNA is constructed of two strands, consisting of sugar molecules and phosphate groups. Between these two strands are nitrogen bases, the compounds which make up organisms’ genes, with hydrogen bonds between them. Those hydrogen bonds have sometimes been seen as crucial to holding the two strands together. But now, researchers from […]

Robin Wakeling The complex 2D structures observed in microscopic images of COVID-19 vaccine samples has raised concerns about the presence of graphene oxide. However, the presence of 2D crystalline structures per se are probably not signatures of graphene oxide but are signatures of something else, something more profound perhaps. … Perhaps the appearance of these […]
