"Footprinting," or DNase protection, is a technique used to identify:

A) a region of DNA that has been damaged by mutation.
B) E. coli cells that contain a desired, cloned piece of DNA.
C) the position of a particular gene of a chromosome.
D) the position of internally double-stranded regions in a single-stranded DNA molecule.
E) the specific binding site of a repressor, polymerase, or other protein on the DNA.
