Shortly after, Watson and Crick made a crucial advance when they proposed that the DNA molecule was made up of two chains of nucleotides paired in such a way to form a double helix, like a spiral ...

The famous DNA double helix is considered right-handed, meaning its spiral strands — a sugar-phosphate backbone — twist to the right. (To picture this, make a thumbs-up with your right hand ...

The DNA molecule was composed of the traditional sugar backbones and nucleotide pairs, but rather than the well-known right-handed spiral of the double helix structure, famously discovered by Watson ...

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 ...
