D) location of a DNA binding protein on DNA.

Question

Quizplus · Accepted Answer

DNA footprinting involves exposing a region of DNA to a DNA binding protein and then cleaving the DNA at the sites where it is not protected by the protein. The resulting pattern of DNA fragments reveals the location of the protein on the DNA, allowing for identification of specific binding sites and inference of the protein's functional role. Therefore, the information gained from DNA footprinting is the location of a DNA binding protein on DNA.
