The double helix is a description of the molecular shape of a double-stranded DNA molecule. In 1953, Francis Crick and James Watson first described the molecular structure of DNA, which they ...

Instead of binding to DNA through the insertion of an α-helix into the DNA major groove — a motif which is used by the ubiquitous helix–turn–helix family of transcription factors — RHH ...

Franklin, working mostly alone, found that her x-ray diffractions showed that the "wet" form of DNA (in the higher humidity) had all the characteristics of a helix. She suspected that all DNA was ...

Researchers at the Chambers University of Technology have discovered that water is why DNA strands are wrapped around each other and have a helix shape. Understanding how DNA repairs itself could ...
