Copies of the DNA exit the nucleus to be read and translated into proteins in the cell cytoplasm. The transit between the nucleus and the cytoplasm takes place through the nuclear pores, genuine "customs agents" that monitor the import-export between these two compartments. Researchers have just discovered how nuclear pores also regulate the production speed of these DNA copies.
