Most biochemistry labs that study DNA isolate it within a water-based solution that allows scientists to manipulate DNA without interacting with other molecules. They also tend to use heat to separate ...

In a way, sequencing DNA is very simple: There's a molecule, you look at it, and you write down what you find. You'd think it would be easy—and, for any one letter in the sequence, it is. The problem ...

A new family of enzymes enables precise cuts in single-stranded DNA, offering powerful new tools for genetic engineering and expanding possibilities in biotechnology. (Nanowerk News) A few years ago, ...

For the first time, scientists have witnessed the very moment DNA begins to unravel, revealing a necessary molecular event ...

Similarly to the artistic technique of folding paper into ornate shapes, DNA origami is a self-assembling technique of precisely folding single-stranded DNA scaffolds into well-defined nanostructures.

Not all DNA looks like the familiar double helix. Sometimes, parts of our genetic code fold into unusual shapes under certain conditions. One such structure known as a G-quadruplex (G4) looks like a ...

An INRS team discovers a new family of enzymes capable of inducing targeted cuts in single-stranded DNA . A few years ago, the advent of technology known as CRISPR was a major breakthrough in the ...

Researchers have unveiled a way to flip genes back on without slicing into the genome, a shift that could make CRISPR far safer and more flexible. Instead of cutting DNA, the new approach scrubs away ...
