DNA, the blueprint of life, is best known for its fundamental role as genetic material—storing and transmitting biological information through the precise sequence of its bases. For decades, this ...

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 ...

Every person starts as just one fertilized egg. By adulthood, that single cell has turned into roughly 37 trillion cells, many of which keep dividing to create the same amount of fresh human cells ...

Scientists have discovered that DNA behaves in a surprising way when squeezed through tiny nanopores, overturning a long-held ...

Mutations are changes in the molecular "letters" that make up the DNA code, the blueprint for all living cells. Some of these changes can have little effect, but others can lead to diseases, including ...

Plectonemes are the analog of the twisted tangles of telephone cords, and can form in DNA that is pulled through a nanoscale channel. They are called plectonemes. They are the analog of the twisted ...

Next-generation sequencing (NGS) has made analyzing DNA faster and cheaper, with effects felt in the lab, clinic, and beyond. A set of newly-launched technologies are offering a twist on the chemistry ...
