Researchers explain process by which cells 'hide' potentially dangerous DNA segments
The DNA in the 23 pairs of chromosomes in each of the billions of cells of the human body is so tightly packed that it would measure six feet in length if stretched end to end. A genome of this size can squeeze into a cell's ...

Researchers 'unzip' molecules to measure interactions keeping DNA packed in cells
(PhysOrg.com) -- Anyone who has ever battled a stuck zipper knows it's a good idea to see what's stuck, where and how badly -- and then to pull hard. A Cornell research team's experiments involve the "unzipping" ...

Biologists discover link between CGG repeats in DNA and neurological disorders
Researchers have long known that some repetitive DNA sequences can make human chromosomes "fragile," i.e. appearing constricted or even broken during cell divisions. Scientists at Tufts University have found that one such ...
