A new study finds that mitochondria in our brain cells frequently fling their DNA into the cells' nucleus, where the mitochondrial DNA integrates into chromosomes, possibly causing harm. As direct ...

Gene therapy holds the promise of preventing and curing disease by manipulating gene expression within a patient's cells.

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 ...

One of the most detailed 3D maps of how the human chromosomes are organized and folded within a cell's nucleus is published in Nature. Subscribe to our newsletter for the latest sci-tech news updates.

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 found DNA in the nucleus of brain cells, where it shouldn’t be. Bits of genes that typically reside in mitochondria insert themselves at unexpectedly high rates into brain cells’ ...

One of the most detailed 3D maps of how the human chromosomes are organized and folded within a cell's nucleus is published in Nature. Chromosomes are thread-like structures that carry a cell's ...

Mitochondria release segments of mitochondrial DNA that can travel through pores of the nucleus and integrate into a cell's chromosomes (where the insertions are called NUMTs, for nuclear ...
