Within a cell, the nucleus is surrounded by the nuclear envelope—two layers of phospholipid membrane that prevents the nucleus mixing with other parts of the cell, thus protecting the cell's DNA from ...

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 ...

Researchers at the Francis Crick Institute have shown that the 'pacemaker' controlling yeast cell division lies inside the nucleus rather than outside it, as previously thought. Having the pacemaker ...

Researchers have found hundreds of metabolic enzymes attached to human DNA inside the cell nucleus. Different tissues and cancers show unique patterns of these enzymes, forming a “nuclear metabolic ...

The image shows the cross section mutant brown adipose tissue section with enlarged lipid droplets (yellow) and nucleus (blue) being impinged by multiple mitochondria (red). Mitochondria are ...

Imagine trying to poke a hole in the yolk of a raw egg without breaking the egg white. It sounds impossible, but researchers at the University of California San Diego have developed a technology that ...
