DNase-1 footprinting is used to study the interaction of proteins with DNA. It involves treating a DNA sample with DNase-1, which cleaves the DNA at random positions. However, if a protein is bound to the DNA at a specific site, it will protect that site from cleavage by the DNase-1. The resulting pattern of cleavage products can be visualized by gel electrophoresis and used to determine the binding site(s) of the protein on the DNA molecule.
