Anyone who has ever battled a stuck zipper knows it's a good idea to see what's stuck, where and how badly -- and then to pull hard. New experiments involve the "unzipping" of single DNA molecules. By mapping the hiccups, stoppages and forces along the way, scientists have gained new insight into how genes are packed and expressed within cells.
