(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 ...

In recent years, people have claimed to suffer from a rather odd disorder. It takes the form of electrosensitivity, and its victims complain of headaches, nausea, and a multitude of other symptoms.

It is only now that the DNA bond modification process has been accurately quantified, and its quantum element understood. (Courtesy: Shutterstock/ymgerman) Quantum effects play a hitherto unexpected ...

WITHOUT them, life as we know it could not exist, yet the exact definition of the hydrogen bond – credited with keeping water liquid and giving DNA its signature helical shape – has always been fuzzy.

Hydrogen bonds are at the very core of life as we know it, and now for the first time ever scientists have managed to visualize these transient molecular associations. This technique can be used to ...

Figure 2: Autoradiogram of denaturing polyacrylamide gels showing single-nucleotide insertions with a, A or Z in the template strand and b, using dATP or dZTP as the nucleotide substrate. Figure 3: ...

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 ...

Open an introductory chemistry textbook. What is a covalent bond? A covalent bond occurs when atoms share electrons in a molecule. What is a hydrogen bond? A hydrogen bond is an electrostatic ...

Using a technique called high-resolution atomic force microscopy (AFM), researchers in China have visualized the molecular structure of a hydrogen bond. Image: AFM images of 8-hydroxyquinoline on a ...
