Nuclear-pore complexes are elaborate protein scaffolds that sit in the membrane around a cell's nucleus.
They do this by interfering with the activity of the messenger RNA strands that transfer genetic information from the cell's nucleus to its protein-making machinery.
This week, the Forbes Luxury Housing Index indicates that the tech-industry's nucleus remains resistant to the downturn, at least relative to other, harder-hit California areas.
In addition to taking normal images of the impact in the visible spectrum, the HRI provides an infrared "fingerprint" of the material from inside the comet's nucleus.
ALS6 is a protein normally found inside a cell's nucleus, but in patients with Lou Gehrig's disease, it is found outside the nucleus and sometimes forms unusual clumps.
CNN: Gene linked to some cases of Lou Gehrig's disease found
The treatment involves loading a functional gene onto a fragment of a deactivated virus that transports the gene to a cell's nucleus, where it is intended to take over.
It's never happened before that we've fired a very large bullet that's made largely of copper and aluminum, the size of a washing machine, at a comet that's about--the comet's nucleus is about four or five miles across--to make a big crater.
The viruses in question were retroviruses, which work by adding their genes to those of their host's cell nucleus.
At the rail trail's end, Bright is northeast Victoria's cycling nucleus.
"It's been important to keep the nucleus as even to replace the few we have lost is a big ask, " he said.
This technology, which Dow AgroSciences is moving toward the market, is called a zinc finger, a naturally occurring protein that can be used in a cell nucleus like an editor's red pencil.
Lead, being heavier than tin, has more protons in its nucleus (82, against tin's 50).
He considers the customs union between Russia, Belarus and Kazakhstan, which comes into effect on January 1st 2012, as the nucleus of a Russian equivalent of the European Union's growth-boosting integration.
South Korea's researchers have taken egg cells from volunteer women, removed the nuclei from those cells (which contain only half of the genetic complement required to make a human being, since the other half is provided by the sperm), and replaced each nucleus with one taken from one of the volunteer's body cells (which contains a full genetic complement).
After the holes were drilled, it took a couple of hours to place the bundles of electrodes in an area of the brain called the subthalmic nucleus (STN), which is over stimulated in patients with Parkinson's disease.
