The technique that provides the most direct information about the physical, three-dimensional structure of ion channels is:



  1. the sequencing of the channel's amino acids.
  2. physiological measurements of ion selectivity.
  3. X-ray crystallography.
  4. fluorescence imaging of channel subunit dynamics.
  5. All of the above provide similar information on the channel's three-dimensional structure.
