Prevalence of Quadruplexes in the Human Genome. Nucleic Acids Res. 2005, 33, DNA Helix: Pi stacking interactions are a key, potentially dominant, stabilizing feature of DNA’s helical structure. As the aromatic nucleobases orient to engage in favorable pi-pi interactions, this influences a second stabilization event: interstrand hydrogen bonding between base pairs. Adenine Guanine Cytosine Thymine DNA Bases Designates base stacking G-quadruplex: Four guanine bases arranged in a square planar manner can engage in the non-covalent interaction of hydrogen bonding to form a G-quartet. Stacking of G- quartets forms a G-quadruplex. Stability of this complex increases with the number of stacked G-quartets due to the stabilization afforded by pi-pi interactions. In the core of these guanine complexes, which are lined with partially negatively charged oxyegns, cations may coordinate to afford additional stabilization. In v...

People work together when it suits them. They’re loyal when it suits them. Love each other when it suits them. And they kill each other when it suits them.
