The role of electrons and their negative charge in electric current is well established. Electrons also exhibit other ...

It is now ~50 years since the discovery of the atomic structure of the α-helix by Linus Pauling. Like the other great helical structure in biology, the double helix of B-DNA, it was ultimately ...

the helix structure is unwound special molecules break the weak hydrogen bonds between bases, which are holding the two strands together this process occurs at several locations on a DNA molecule ...

Electrons have a hidden feature — spin — that could revolutionize technology. Magnets can control it, but researchers are now ...

James Watson (left) and Francis Crick (right) report in Nature the discovery of the double-helix structure of the DNA molecule. Papers from Rosalind Franklin and Maurice Wilkins, which appear ...

A mantis shrimp's punch creates high-energy waves. Its exoskeleton is designed to absorb that energy, preventing cracking and tissue damage.

However, the structure of the winged-helix protein, hRFX1, bound to DNA reported in a recent issue of Nature 1 has revealed a striking counter example to this rule. Figure 1: Structure of two ...

Scientists still needed to figure out this molecule's structure to be sure, and to understand how it worked. In 1948, Linus Pauling discovered that many proteins take the shape of an alpha helix ...

DNA is a complex molecule that consists of two strands coiled around each other to form a double helix structure. Comparison of a single-stranded RNA and a double-stranded DNA with their corresponding ...

Chances are you've seen an illustration of DNA's double-helix structure and even pictures of the chromosomes that comprise the human genome. But where and how does the famous double helix fit into ...
