DNA is packaged tightly within the cell’s nuclear membranes, which contain channels that regulate the transit of macromolecules governing all of life’s functions. Yale University researchers have built a nanoscale replica of this channel and have visualized the interaction of proteins that act as “molecular bouncers,” controlling access to the channel’s 40-nanometer entrance.
