When DNA inside the nucleus of a human cell is damaged, a specific network of microtubule filaments forms in the cytoplasm ...

In eukaryotic cells, the membrane that surrounds the nucleus — commonly called the nuclear envelope — partitions this DNA from the cell's protein synthesis machinery, which is located in the ...

Just as cities must carefully manage the flow of cars in and out of downtown, cells regulate the movement of molecules into and out of the nucleus.

The nuclear pore is a protein-lined channel in the nuclear envelope that regulates the transportation of molecules between the nucleus and the cytoplasm. In eukaryotic cells, the nucleus is ...

Eukaryotic cells store their DNA in the nucleus, cordoned off from the cytoplasm by the nuclear envelope. Made up of two lipid bilayers called the inner and outer nuclear membrane, the nuclear ...

The nuclear envelope is a regulated membrane barrier that separates the nucleus from the cytosol in eukaryotes. Although the NE is often depicted as a static barrier, new research has identified ...
