A Scanner for Hereditary Defects

Caption

The XPD scanner (green)is in close contact with a damaged point (red) on the DNA double helix. The damaged DNA strand lies in a deep pocket of the protein to enable a ferrous sensor (Fe) to come into contact with the damaged point, thereby halting the protein as it moves along the DNA.
