DNA is a two-stranded molecule that appears twisted, giving it a unique shape referred to as the double helix. Each of the two strands is a long sequence of nucleotides. These are the individual ...

Solid-state nanopores can act as single-molecule sensors and could potentially ... nm thick (equivalent to the spacing between two bases in a DNA chain) and could therefore provide a suitable ...

Cohesin is a protein that forms a ring-shaped complex which wraps and alters the DNA molecule shape. It moves through the DNA ...

In our last installment on DNA sequencing, we brought you up to speed on the Sanger method of sequencing (named after its dual-Nobel-winning inventor, Fred Sanger), which was state-of-the-art ...

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 ...

Francis Crick and James Watson with a model of the DNA molecule At midday on 28 February ... in the nearby Cavendish laboratory, the two scientists had discovered the structure of deoxyribonucleic ...

DNA polymerases are enzymes that create DNA molecules by assembling nucleotides, the building blocks of DNA. These enzymes are essential to DNA replication and usually work in pairs to create two ...

A team at Nagoya University experimented with ways to uncurl a DNA molecule using pressure applied to liquid flowing in a channel, with the pressure flow providing shear force that uncurled the ...
