Hydrogen bond strength in DNA: where 3 could be less than 2

Nanowerk.com - 10 октября, 2017 - 11:32
Hydrogen bond base pairing forces are essential for the mechanisms associated with DNA stability. Despite attracting great research attention, this fundamental interaction has eluded a precise physical description so far since its electrical origin has not been quantified yet. Researchers now have proposed characterization by means of electrical forces, providing a framework for universal characterization of hydrogen bonds. In this way, they provide technical arguments to support that hydrogen bonds are well distinguishable and their role in biological events require a proper specific intrabond description.
