When long DNA chains that had been added to the water went through the opening one-by-one, they blocked the flow of ions, resulting in a change in the electrical signal. The exact nature of those changes allowed the researchers to determine the size of each DNA molecule, and to identify their individual nucleobases, which are the letters of their genetic code.
