Question

DNA footprinting is the technique used to identify the specific DNA sequences, such as promoter regions, that proteins bind to. This method involves treating a DNA-protein complex with a DNA-cleaving agent, removing the protein, and then analyzing the DNA fragments. The protected region (where the protein was bound) can be identified because it is not cleaved, hence "footprinting" the location of protein-DNA interactions.
