As warehouses go, nuclei are more like libraries than bank vaults. Too many cellular components need access to the genome to ...

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 ...

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.

Each nuclear pore complex (NPC) consists of more than 1,000 individual protein subunits with a total molecular mass of approximately 120 million daltons—the equivalent of more than 6.5 million water ...
