(Nanowerk Spotlight) Hydrogen bond base pairing forces are essential for the mechanisms associated with DNA stability. Despite attracting great research attention, this fundamental interaction has ...

Scientists have long known that protons hop along hydrogen-bond pathways in these systems. What they couldn't pin down was ...

Scientists at the Chalmers University of Technology in Sweden say they have disproved the prevailing theory of how DNA binds itself. It is not, they claim, as is generally believed, hydrogen bonds ...

An asymmetric kleisin path breaks the symmetry of the SMC homodimer, ensuring unidirectional DNA translocation via a segment capture mechanism.

For the first time, researchers have succeeded in developing an artificial DNA base pair that is based on a different chemical force than natural genetic material. While the common natural DNA ...

(Nanowerk News) Hydrogen bonds are of fundamental interest in materials science, physics and chemistry. An international team including scientists from the University of Bayreuth has now achieved ...

There are four bases: Adenine and Guanine (purines); Cytosine and Thymine (Pyrimidines). Purines have two carbon-nitrogen rings while pyrimidines have a single carbon-nitrogen ring. Thus, there are ...

Although they are much weaker than the preeminent "covalent" chemical bonds that bind atoms in biological molecules, hydrogen bonds are known to occur at key points along the central "backbone" ...
