The secret to cellular youth may depend on keeping the nucleolus—a condensed structure inside the nucleus of a cell—small, according to Weill Cornell Medicine investigators. The findings were ...

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 ...

The artificial cell nucleus (right) constructed using the purified DNA was morphologically very similar to the natural cell nucleus derived from an egg (left). A team led by Professor Kazuo Yamagata ...

Scientists have elucidated the molecular mechanism by which LEM-3 cuts DNA bridges during cytokinesis. If DNA bridges persist between chromosomes during cell division, chromosomes are abnormally ...
