In diagrams and illustrations of cells, DNA is sometimes shown as a mass in the cell's nucleus, like a bowl of ramen noodles. For many years, it's been standard practice to take images of cells that ...

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 ...

Paleontologists have isolated cartilage cells from an exceptionally well-preserved dinosaur fossil in China. The cells' nuclei still contain traces of biomolecules and other organic structures, and ...

Researchers at Karolinska Institutet in Sweden have developed a new sequencing method that makes it possible to map how DNA is spatially organized in the cell nucleus - revealing which genomic regions ...

COLD SPRING HARBOR, N.Y. (Nov. 30, 2010) --The nucleus of a cell contains its DNA and is the site where DNA replication, transcription, and RNA processing take place. Within the nucleus, nuclear ...

This narrated animation illustrates the process of protein synthesis, starting with chromosomal DNA inside the cell's nucleus. A gene is transcribed into messenger RNA, which leaves the nucleus and ...
