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 ...

Here is a view of the double helix -- the subject of Rosalind ... structure resembles a twisted ladder. Note also that DNA with a "left-handed" twist, as this has, is a special kind of DNA known ...

that the DNA molecule exists in the form of a three-dimensional double helix. More than 50 years passed before the significance of Miescher's discovery of nucleic acids was widely appreciated by ...

A new method for mapping torsion provides insights into the ways that the genome responds to the torsion generated by RNA polymerase II.

In 1953, Francis Crick and James Watson described the molecular shape of DNA as a "double helix." Double-stranded DNA is composed of two linear strands that run opposite to each other, known as ...
