Not all DNA looks like the familiar twisted ladder. Sometimes, parts of our genetic code fold into unusual shapes. One such structure, the G-quadruplex (G4), looks like a knot. These knots can play ...

DNA's iconic double helix does more than "just" store genetic information. Under certain conditions, it can temporarily fold into unusual shapes. Researchers at Umeå University, Sweden, have now shown ...

New research sheds light on how cells repair damaged DNA. For the first time, the team has mapped the activity of repair proteins in individual human cells. The study demonstrates how these proteins ...

Researchers have found that the way DNA is packaged in cells can directly impact how fast DNA itself is copied during cell division. They discovered that DNA packaging sends signals through an unusual ...

A research team led by Professor ZHANG Na from the High Magnetic Field Laboratory, Hefei Institutes of Physical Science, Chinese Academy of Sciences, has determined the first atomic-resolution ...

Researchers at Nano Life Science Institute (WPI-NanoLSI), Kanazawa University and colleagues have achieved a breakthrough in understanding sperm DNA packaging. Using high-speed atomic force microscopy ...

While most known types of DNA damage are fixed by our cells' in-house DNA repair mechanisms, some forms of DNA damage evade repair and can persist for many years, new research shows. This means that ...

James Dewey Watson, whose co-discovery of the twisted-ladder structure of DNA in 1953 helped launch a revolution in biology and medicine, died Thursday at age 97. He died in hospice care after a brief ...
