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 ...

Scientists show that positively charged metal ions help DNA molecules overcome electrostatic repulsion, supporting the DNA ...

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 ...

An essential cellular enzyme successfully transcribed synthetic DNA letters, bringing expanded genetic codes closer to ...

Researchers at the University of Rochester thought that shutting down a protein linked to inflammation might help slow aging.

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 ...

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 ...

A molecular illustration of the crowded interior and cell envelope of Escherichia coli. (David S. Goodsell, The Scripps Research Institute) To replicate information, life usually has fairly ...

Thymine modified polymer for delivering DNA into cells. A thymine modified compound, poly (ethylene glycol) (PEG), is bound to DNA through an annealing process, then delivered by intramuscular ...
