Every cell in the human body squeezes over six feet of DNA into a miniscule speck invisible to the naked eye—like compressing ...

Activated immune cells secrete tiny capsules bearing DNA that can enter other immune and tumor cells to stimulate the body's ...

DNA replication is usually a very precise, templated process, but some enzymes are capable of "doodling," which might lead to ...

Cell division is one of the most fundamental and complex processes underpinning life. In human cells, thousands of molecules ...

Researchers have built a platform that programs short DNA fragments inside living cells to control protein activity, all without editing or altering the cell’s genome. The system, published in Nature ...

Scientists at Durham University, working in partnership with Jagiellonian University in Poland, have developed a new ...

The left-handed spiral of each Z-DNA strand is highlighted on the left. Binding and bonding of the two zinc finger domains (shown in red) from the CTCF protein to Z-DNA (shown in blue). This protein ...

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 ...

Cyanobacteria—ancient microbes that oxygenated Earth and made complex life possible—are still revealing surprises billions of ...

The DNA inside our cells is constantly being damaged, and one of the worst kinds of damage is a double-strand break-when both sides of the DNA helix are cut at once. Healthy cells can normally fix ...

Defeating obesity is rarely easy. For many people, even successful weight loss is followed by a prolonged struggle to prevent ...
