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 ...
Physicists Maria Goeppert Mayer and J. Hans D. Jensen develop a theory of the nucleus as composed of shells of protons and neutrons. It explains why nuclei ...
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 ...
(A) Experimental design. (B) Behavior assessments using open field tests. Heatmaps illustrate time spent (red) and movement trajectories (green). The PD group exhibited decreased movement speed ...
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 ...
The investigations of KIT researchers have shown that biomolecular condensates enable fast yet reliable activation of the right genes. “Biomolecular condensates are tiny drops that form in specific ...
