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 ...

Cancer genomes are the result of diverse mutation processes that have often accumulated over decades. Scientists have analyzed the molecular evolution of tumors after exposure to mutagenic chemicals.

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 ...
