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 ...

If stretched out, human DNA would be about 2 meters long. For this long strand to fit inside the cell nucleus, which is about ...

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 ...

Inside every human cell, six feet of DNA folds into a nucleus that is only a few micrometers wide, yet still manages to ...

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

A tiny percentage of our DNA—around 2%—contains 20,000-odd genes. The remaining 98%—long known as the non-coding genome, or ...

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 ...

Lipid membranes, which form the outer layer of cells, can be engineered to influence cellular functions. For example, adjusting the permeability of the membrane can improve drug delivery. Adding ...

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 ...

DNA can sustain serious injuries called double strand breaks, in which both strands of the helix snap. These breaks are among ...
