A sticky end is a short single-stranded overhang protruding from the end of a double-stranded helical DNA molecule. Like flaps of Velcro, two molecules with complementary sticky ends — that is ...

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 ...

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

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 ...

Roche has put forward a new approach to genetic analysis, which it describes as sequencing-by-expansion—a proprietary method that pulls apart the DNA molecule ... fruit of two of Roche’s ...

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 ...

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 ...

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 ...
