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 ...

Those 'DNA knots' weren't knots at all, and the truth is stranger
For decades, biology textbooks taught that DNA’s story could be told with a single image: two elegant strands twisting in a ...

AI uncovers 360,000 DNA knots that quietly shape how genes turn on and off
Scientists have created the first comprehensive map of DNA quadruplexes, fleeting knot-like structures that play an outsized ...
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 ...
For stem cells to differentiate into the appropriate cell-type, transcription factors (TFs) must be tailored to highly specific expression patterns of lineage-specific genes. Abnormalities in the ...
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 ...
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 ...
Researchers have revealed that so-called “junk DNA” contains powerful switches that help control brain cells linked to Alzheimer’s disease. By experimentally testing nearly 1,000 DNA switches in human ...
Researchers have identified elusive DNA switches in brain support cells that influence genes tied to Alzheimer’s disease. When people think about DNA, they often picture genes that determine our ...
Mathematicians uncover a method to control cellular noise, offering a new way to prevent cancer cells from surviving and ...
