Cooperation and selfishness both benefit the donor and therefore should be favoured by natural selection.

We perform DNase footprinting by binding the protein to its DNA target, then digesting the DNA–protein complex with DNase. 

When we electrophorese the resulting DNA fragments, the protein binding site shows up as a gap, or “footprint,” in the pattern where the protein protected the 

DNA from degradation.
