DNase I hypersensitive sites

DNase I hypersensitive sites are regions in the DNA that are more accessible and open, allowing enzymes like DNase I to cut easily. These sites typically mark areas where regulatory elements, such as gene switches and binding sites for proteins that control gene activity, are located. Because they are open and unwrapped, they enable important genes to be turned on or off as needed. Detecting these hypersensitive sites helps scientists identify key parts of the genome involved in gene regulation and understanding how genes are controlled in different cells.
