Which of the following techniques may be used to determine DNA-protein interactions?
A) Western blotting
B) PCR
C) DNAse I foot printing
D) Restriction enzyme analysis

Question

Quizplus · Accepted Answer

DNAse I foot printing is a technique used to determine DNA-protein interactions. It involves the use of DNAse I, an enzyme that cleaves DNA at specific sites. When DNAse I is incubated with a DNA sample that is bound to a protein, the protein will protect the DNA from cleavage at the sites where it is bound. This results in a pattern of cleavage that can be used to determine the location of the protein binding sites.
