Researchers have reported X-ray crystal structures of bulk LiP and LiAs containing spiral and coaxial chains, but it remained unclear as to whether they should be called double-helix structures.

Naturally occurring DNA forms a linear chain, like a long piece of twine ... The branches form when the double helix partially unravels into two strands. In replication, each strand is made ...

Fifty-nine years after James Watson and Francis Crick deduced the double-helix structure of DNA ... across the ages can reveal migrations of Iron-Age people and genes that protected against ...

A new paper based on long-lost documents confirms that DNA discoverer Rosalind Franklin should be credited for discovering the double helix ... DNA as a "big helix with several chains," according ...

The control of artificial double-helical structures ... The conformation of chiral chains introduced into the helix strands was found to be important for this M/P switching.

Each DNA strand within the double helix is a long, linear molecule made of smaller units called nucleotides that form a chain. The chemical backbones of the double helix are made up of sugar and ...

Double-helical foldamers are one such ... The conformation of chiral chains introduced into the helix strands was found to be important for this M/P switching. Furthermore, they found that when ...
