In human cells, there are about 20,000 genes on a two-meter DNA strand—finely coiled up in a nucleus about 10 micrometers in diameter. By comparison, this corresponds to a 40-kilometer thread packed ...

Scientists have created the first comprehensive map of DNA quadruplexes, fleeting knot-like structures that play an outsized ...

Every cell in a body contains the same genetic sequence, yet each cell expresses only a subset of those genes. These cell-specific gene expression patterns, which ensure that a brain cell is different ...

Researchers have discovered how cells activate a last-resort DNA repair system when severe damage strikes. When genetic ...

The human cell is a miserable thing to study. Tens of trillions of them exist in the body, forming an enormous and intricate network that governs every disease and metabolic process. Each cell in that ...

Scientists mapped hidden DNA switches in brain support cells to understand how gene control may influence Alzheimer’s disease ...

Researchers have revealed that so-called “junk DNA” contains powerful switches that help control brain cells linked to ...

RIVERSIDE, Calif. -- A previously unknown type of DNA damage in the mitochondria, the tiny power plants inside our cells, could shed light on how our bodies sense and respond to stress. The findings ...

One of the biggest quests in biology is understanding how every cell in an animal's body carries an identical genome yet ...

Now, researchers at UNSW Sydney have discovered a group of these switches that help control how brain cells called astrocytes ...
