1. The lane that corresponds to human chromatin before being digested by micrococcal endonuclease is
2. The lane that corresponds to human chromatic treatged with 4% paraformaldehyde, a chemical cross linked that "glues the proteins to the DNA, therefore keeping proteins from ever falling off from the DNA, and subsequently digested with micrococcal nuclease for 12 hours.
3. The lane that corresponds to human chromatic digested with micrococcal nuclease for a relatively short amount of time (about 30 minutes)
4. The lane that corresponds to human chromatin
5. The lane that corresponds to human chromatin digested with micrococcal nuclease for ab intermediate amount of time (about 2hrs is)
6. The lane that corresponds do human chromatin being digested with micrococcal nuclease for a long time (about 4 hours) is
7. A sample digested for only about 30 minutes (short digestion)
